The big-bore option is THE single-most modification that makes the Enfield 650s come alive; as you said about half again (47hp to nearly 70hp on the 863cc) and about another third (47hp to 60-ish on the 743cc), very much worth the effort and money spent. You can buy a new Interceptor, add the big-bore kit, modify the suspension, upgrade the brakes, add a full stainless-steel exhaust system and the FuelX Pro for $2,500 less than the cost of a new Speed Twin 900cc and have the same or better performance. How do I know? I have a 2020 Interceptor with all the options mentioned; cost of the bike new $5599 plus the "750cc" kit, machine shop fees and parts: 8 head bolts, cylinder base gasket etc with my labor was $7,175. The bike has 47,000 miles; I installed the kit 20,000 miles ago when it was 3 years old.
@@frederickwoods5943 , do you use the 650 insurance or have you changed the agreement for a much higher cc agreement 🤔?.
Peace out ✌️
How are the vibrations after the upgrade?
@@andrewbull3537 not an issue in the United States. We have mandatory State Inspection every 12 months in Virginia; nobody rocks the boat..
@@VladKubrat barely noticeable on the "750", but very much an issue with the larger/heavier pistons; my 750INT has 47,000 miles and 20,000 of those miles at 743cc.
@@frederickwoods5943 , ok thanks for your answer 👍, i only asked because over here in france / England (I'm an Englishman now living in france ) if we had an accident the insurance company Could ask for a complete investigations, and if they find the bike has had an upgrade they more than likely wont pay anything 😣.
But i think i might risk it 😁,
Peace out ✌
Truly representative of old school British Engineering. Keep it up.
so the kit os not reliable?
I've done the 865cc big bore kit and other mods on my Interceptor ,It's the best thing to do on the twins if your after a "bigger" feeling motor, make's a good bike into a fantastic one.
@@ivananda865ccinterceptor how much does it increase vibrations?
@andrewhayes4246 Yes, there are more vibrations, not a lot more, I only noticed it when I first did the 865cc upgrade. I don't mind it now. I also own a 411 Himalayan and my modified 865cc is still smoother than the 411.
@@ivananda865ccinterceptor adding bigger pistons always does that. So long as the vibes are low frequency it isn't so bad.
Nice bike.How does 865 kit affect the fuel consumption?
Bear 650 mods, can't wait.
A 500cc kit for the J-series 350 bikes would have a lot of takers. No sign of RE introducing a bigger air-cooled single, as far as I'm aware.
I have heard that its not possible because of the internal design of the block it is not made considering that, these 650s are made to be further developed into 750 and 865cc engines
Good idea. The new 650 classics do not appeal to me. To me, the classic must be a single.
@@premminocha1665 I'm not an engineer, but when I've had the rocker box off there seems to be quite a bit of spare metal. Or could Hitchcocks simply make a bigger top end like the 650 > 865?
Himalayantools sell big bore kits for the 350s. They recommend to go for the 410cc upgrade, it's less hassle. But they also have a 500cc kit.
A Hitchcock approved big bore kit or a turbo 350 J series kit will sell n the US....I don't drive V8 cars... I turbo n nitrous 4 bangers .... If it's built , we will buy
I’ve gone as far as air filter, full exhaust and FuelX. Very happy with additional performance. My insurer in Australia allows me to declare mods.
I have the super meteor and have only added rhino racing mufflers and a dna air cleaner filter. Happy with the additional performance and frankly, tours all day at highway speeds and overtaking is not an issue. Usually in 6th gear. Not knocking the kits, they are the ducks nuts, but nearing 71 I do not need the extra power lol
I have a shotgun 650...thinking about doing these things too!
@@DarrenMiddletonMusic DNA stage 4 filter is simple to install, as are the mufflers. You can buy the mufflers direct from India and have them shipped to whatever country you live in. Just remember, whether you do both together or separately, run the engine at idle only for approx 10-15mins to allow the ecu to recalibrate. Cheers
@@phillgeraldton Great, thanks for the tips mate. I have Rhino mufflers on already...but will look at DNA filter as I read quite a bit about them.
As the saying goes "There's nothing that beats cubic inches" informative vid! Thanks for putting it together 🙂
Wut???? Are you talking about there’s no replacement for displacement ??
The saying that I grew up with goes "nothing beats cubic inches, apart from rectangular dollars"...:-)
Great! Now I have a new bucket list 😂
BUT don't forget to upgrade the breaking system. Adding that much more power will require better breaks.
I have a 2023 Super Meteor 650.
I have installed the DNA filter but also Rhino Racing slip ons, a Fuel pro+ which has the possibility to add fuel to correct the A/F ratio and a belt drive with a higher gear ratio. What I wanted was some more sound, getting rid of the jerkyness and mess caused by the fatty chain, a smoother drive with less RPM in 6th gear and avoid damage to the engine caused by a leaner condition. For this I will check my plugs regulary. I have a totally different and better bike now.
And yes, it has costed some money but for me it was woth it. I also own a Honda VTX 1800 which is a power cruiser so getting more power on my Super Meteor 65 was not my concern.
I tuned the standard Bosch ECU on my bike. It runs great and no piggyback wire mess needed! I am not sure about the later models with the Continental ECU's but it probably is also possible to tune these. The ECU needs to be removed though, so it's a bit more of a bother. Also needed some dyno verification, but the short term and long term fuel trim gave the clues I needed to properly dial it in.
Great concise video, made me realize what an old fuddy duddy I am only replacing exhaust and air filter! 😊
That was a very informative video, that might have been a bit better had you included the prices of each item.

awesome guy love to try all that out like other commenter said "BRILLIANT STUFFS" 🔥🔥🔥
Fantastic!
What a vast improvement !! Now, do you imagine doubling , or at least drastically improving the the power of the Hntr/350 single range ? 🙂
I'm somewhat surprised you haven't suggested/offered upgrading the braking after this massive performance increase.
The rear brakes of SM650 are good but I don't think they can handle 750 or 865 upgrade
Very good point
The Super Meteor 650 Celestial Blue is the bike I would like EXCEPT... they say it is supposed to be a "Cruiser". I've been traveling full time for over 3 years on my Interceptor 650. The INT650 chain periodic service interval is 1,000KM. I've had to stop riding and service twice a week sometimes. As soon as Bandidos Pitstop came out with belt drive conversion I installed it and haven't had to touch it for 30,000KM. (50,000MI/80,000km on my INT650 now) I couldn't believe Royal Enfield came out with a "Cruiser" and still using a chain, and last I checked the service interval for the chain is now cut to 500KM. I am NOT buying a bike that requires servicing a chain every 500 KM, that's almost every day for me. I sincerely hope you are working on a belt drive conversion so this can truly become the "Cruiser" it deserves to be. I think the Super Meteor 650 Celestial Blue would be my next Royal Enfield. Love your products. Love your service, just got a rear brake pressure switch from you faster than I could from USA dealers. Love your videos. Thank you.
I would not consider cleaning of the chain to much of the big deal. It took max 5minutes.
My GT650 has done 2000 miles since I bought it and the chain hasn't needed adjustment once. Slack is still within what it should be.
I do give it full throttle run to the redline through the gears at least once per journey once the engine is hot so it's fair to say that load is being put through it.
As an O-Ring chain the lube is not as critical as a on a non O-Ring.
Is your bike used in really dusty conditions?
@@veritasvincit2745 It varies.
@@Almecho Thank you.
Get a better chain....
Well done chaps - brilliant stuff 🤘😊...
Sounds like some great mods. However I wonder if the crankshaft and gear box will have the same life vs the standard engine, with all that additional power and torque?
Big bore kit for the 350, please. The Classic must be a single.
A 350 that actually outperforms a 1970's 250 would be a better option right out of the starting gate. All these videos on how great these asthmatic 350's are in 2024 is pure drivel.
@@robmyers985what absolute tosh! If that’s what you think the 350 should do, it’s definitely the wrong bike for you. 🤷♀️
want to see the dyno result of a 500cc kit for 350 engine, thank you❤
it would be great to see what type of suspension upgrades are available for the 650 line.
often a much better thing to change than adding power on power, if the bike handles shi7e why make it faster?
@@ogasi1798 Someone with good riding ability could scare the sh1t out of you with the stock suspension, they don't handle like sh1te at all. How would you lot have survived 1970's bikes....!🙄
This is really interesting stuff. Have you had any communication with insurance companies about these upgrades?
I was thinking the same thing 👍,
I've never told my insurance company of any mods, they'll just want more money...
? Who gives af, why would you even tell them?
A very good stage by stage approach to achieve the desired performance.
How about the J series engine with the Himalayan piston kit?
I think that there are so many 350 owners that would like to see 70 mph cruising speed, to be able to
achieve a bike which your not constantly worrying about getting rear ended on.
The 650 classic might be the answer but theres a lot of 350 fans that would like to see a 30 BHP. 350?
Regards

1:31 Now that the GB350s has arrived in UK. Will you guys please look into making a big bore kit for that bike?
Superb !
Great information. When do you think that you will have any upgrades for the Bear 650? Thanks
I think all these mods would suit the bear 650 as these bikes use the same engine. I’m looking at getting the bear 650 when available in Australia. with these mods would be great 🤙
@ashleywagner2650 ordered mine today. I'm in Brisbane
@@ashleywagner2650 I'm thinking of getting one too, and turning it into a soft adv bike....!! I think being as simple as they are, they'd kill it, as long as you're not trying to do enduro type heroics... I'm also an Aussie..
It's too much for Indians, there is barely any money for food... Who will buy bike, no question bout upgrades.. But watching videos is what we can do.
Liked your video tough.
Thank you.
How about cost for each of the upgrades?
@HitchcocksMotorcycles Can you guys talk the rear suspension options for Super Meteor. I had to preload mine to max even if I ride alone. Rear suspension is the first thing commented by youtubers on Super Meteor. On the other hand your store happens to have extensive range of options to choose from. I would appreciate a little guide.
Good job guys
Mate this is a great video.
Best piece of, to the point advice for the Super Meteor/ Shotgun
Is there any way one can place an order from India?
Hola. Es necesario hacerle algún cambio al radiador para mejorar la refrigeración cuando se la hagan los cambios para mayor potencia?
How do all these mods put extra stress on the bottom end??
It would be good to have a visual scenario with a Standard 650 and your 860 or 650 (presume it is 860) at the same time (Dual). Also half way in between if you have one. Picture paints a thousand words.
Any figures for Fuel economy differences from stock to the 750 and 865 cc's ?
How does the stock suspension and brakes hold up ?
I am in India and would love to upgrade the engine's cubic capacity. However, I cant change the oem exhausts due to legal reasons. I am open to other mods as long as there is no visual difference.
I dont want to go overboard. Would changing only the air filter and increasing engine cc be an improvement?
With changing from 650 to 865 ,do you have to change your insurance and because you've changed the engine capacity do you have to re -register the bike ?
Sorry if it's a stupid question but I'm sure alot of people are thinking the same thing 🤔.
Peace out ✌️
P.s what horse power do you gain and what price for each piece mentioned.
that is up to you - they are internal changes so no inspection post accident would ever know and only a naive rule follower will tell you any different, i would not tell mine in any chance, last time i turned a vehicle upside down it was littered with mods and i got no questions when they paid me out
@@ogasi1798 I agree ,,On my Himalayan the big bore kits been on a couple of yrs (about 25000miles) no issues,,Why would you involve the insurers,,it just gives them an excuse to rip you off (even more) But thats just my opinion,,, really its a no brainer
@@ogasi1798,ok ,thanks for the honest answer 👍
@andrewbull3537 Don't tell them if looks the same they're not gana know.If you put Reverlry 40mm Throttle bodies on it they would notice but if keep stock 36 mm Throttle bodies bike look stock & you're allowed to swap exhausts on full license so may tell them about aftermarket exhaust just because it looks different than stock exhaust but internald can't be seen so they won't know.
I'm surprised these mods work with the Euro 5 bikes. Don't they throw any errors on the dash ? Even the powertronics and dynojet, I didn't think they worked with Euro 5 bikes ? What am I missing/confusing here ?
Would be interested to know Royal Enfields perspective on these modifications. Does it affect the warranty on the bike?
Any mod, whether it enhanced performance or not, will likely affect the warranty.
@@michaelmurdock4607 True. Most authorized service centres would make a fuss and refer the matter to RE.
@@michaelmurdock4607 I don't think it depends on the dealer but on the Roal Enfield company itself which will make the final decision.
Do you do bags for super meteor 350
I have a Hitchcocks 462 cc BBore kit fitted ,,its great I am considering getting a 650twin (probably a Super Meteor) and having fitted the 825 kit,,My question is can the kit ( and clutch and Dyno jet) be fitted without the cams and air filter ,, I do not need loads of extra Hp ,,I am a torque junky ,,I hardly ever go above 5000revs... But I do want a big wallop at 3500 to 5000 revs ???
Are there kits like these for the 411?
Help me out here. Im in australia, so the full upgrade costs nearly a fill 150% of the bike cost. I love that little engine, and would be interested doing this to a shotgun, but for me thats more than the floor cost of a bonnie bobber.
Ultimately its still a heavy bike with famously average switch gear, and metal frame/ chrome of limited lifespan.
Edit: once youve got the juice up above the 65hp mark, what break reccommendation do you have? Ith gt and ceptor already have famously borderline breaks at 49hp and 200+ kg.
Can a increase in power be achieved with a Woolich map ?
Does the stage II cam kit need a clutch upgrade kit as well?
How does the lower end handle that increase ?
Would have been good to see the Fuel X out of the box , ( is it like a V- boast that is fitting on the wiring harness- plug and play and tricks the ECU into delivering more fuel in low RPM to help as you say with the jerkiness ) didn’t care about the cams “ cams are cams “
Tec bike parts has a decent video in which George explains how the Fuel X works.
Ive got a euro 5 interceptor 650, dna filter with adapter plate, tec 2-1 stinger system and a fuel x lite, so if I were to go stage 2 cam or even big bore I need a power commander/powertronic but do they replace or work along side the fuel x? I’d say replace?
Wgat are the torque figures of 750 & 865?
Hi Derek,
Will Hitchcocks be doing an upgrade kit for the Classic 650?
The Classic 650 has exactly the same motor as the other RE 650s. Same motor = same kit.
@@felixVanDiemen ... I wouldn't be so quick to assume that for the exhausts, and I'd even double check the air filter.
So, to confirm, once the cam is in we need the Power Commander correct? If you are doing the cam, pipes and air filter you just get the Power Commander and not the Fuel X correct?
yes - so skip fuel x and go straight to commander if you think you will add cam
Prices please!

bonsoir et le 865 avec arbre a came stage 1 sa donne quoi ?
There must be a big enough market for re to make a 865 model
RE might he in development of a 750cc model in near future.They have ho get it through Emissions so 750cc probably be the go or 800cc with a bigger oil cooler.
RE 750 only be about 57-60hp at the Crank.Buying a 650 & doing Hitchcocks 750-865 will make more power & torque cause ad a private owner not restricted by emissions & use free flowing pipes.If get a RE 750 in future you would want to put big bore headers & air filter & get rid of the heavy restrictive stock pipes.
How much of a decrease in mpg with upgrade?
Im STILL riding my 1980s Iron barrelled Enfield Just stripped it down today to give it a "spruce up" for next year Sorry Allen, while there will be some orders ,,, the boys will still have to drink poundland tea
Is it possible to use fuelX on a 2023 Interceptor? Do they not have anti-tamper ?
I was wondering, and asked, the same thing. The bikes they are demo'ing here are Euro 5, like the 2023 Interceptor 650.
So I'm surprised to see the full suite of mods on display here, and no mention of OBD errors, or any errors being thrown to the dash ... I feel like I must be confused or there must be some new development ? Because I was under the impression that the OBD2 on the Euro 5 bikes caused problems for any of the mods displayed in this video.
As the 650 engines are reported to run very lean when standard, adding a freer flowing air filter is surely going to make it dangerously lean. Wouldn’t an ecu re flash to get the A/F ratio optimised be wise to do at the same time? Rather than mess about with the addition of the Fuel x.
"Your ride, your way" unless you want a black exhaust for the signals 350.
2 years and still waiting.

I like royal en bike but I havas not money
Let’s buy a brand new bike and spend a wedge on making them tiny bit better when inferior to most imo. Don’t get the hype at all.
Just buy a better bike, make it your own happens when you cough up your cash!
There’s always one bell end, and here you are 🙄

Oh wow…goes from 43hp to 44hp! Garbage bikes.
Bell end !😅😅😅

@ I have had a lot of bikes in my 25 years of riding. I test ride a few RE’s and was extremely unimpressed. They are very overpriced in Australia for what you get, even if they look good, I would never own one. I currently have a 23 Low Rider S. What do you ride?
Why are you watch a vid about a motorcycle brand you don’t like?
@ you are absolutely right, this is the last one.
Hello, what's the fuel efficiency like after the big bore kit is introduced?
