I just bought an 81 900 for $70! It is complete except right side exhaust is gone. It has a Vetter Windjammer so the factory headlamp & fork mount tubes are gone. I cranked it over.. has good compression & spark.. I had an 81 750 Custom when I was a young'n.. I didn't know these had the hi-low range so glad I found your informative video
Very cool! Good luck with the restoration. You might want to check out my CB900C playlist. Lots of good CB900C content: ua-cam.com/play/PL0gjN9hf6pSq91QZhddq57LhkoQM_9c6t.html&si=ATt7V3Kda-kBpzYU
Very versatile, actually. I had a new CB900C and later, a CB1000C. If I felt like it, I could leave them in high-range, and skip 2nd and 4th gears, using it as a lazy 3-speed. Short shifts to redline shifts, these bikes have enough stuff to shift about any way you feel like. P.S.: Redline in high-range first is almost 55 mph. Everything after that is optional.
It's a bit hard on the clutch to start off in high range. A lot of bikes are like that. First gear is a bit high, and they give their local motorcycle shop some extra business. So go ahead and start off in high range. Your local shop will like you.
Thank you , i never knew that Honda had this type of Cycle, yes very informative, Japanese built bikes made for the serious biker and maintenance friendly.
I have my eye on one of these bikes and this video was immensely helpful. I won't look like a fool when I go to test drive the bike now! Straightforward and easy to understand. Thank you for posting this!
Excellent video. I had a new 83' CB1000 Custom. Never regretted selling a bike more. Easily the most fun and reliable bike I have ever owned! The next time I find one (which is hard) - I will probably buy it.
Love my Hondas looking for a 750/900 ,had been put off 900c because of the gear, now thanks to your video you have put my mind at rest on how to use them thanks 😁,900 c on it's way 😁😁
Right on, Brian! The 750 and 900 Hondas are good bikes. Good luck in your search. I have lots of 750 and 900 content on this channel. Feel free to check it out. Cheers!
@@brianboucher809 Awesome! Did you see my VTR1000F review that came out this morning? Cheers! ua-cam.com/video/hbax38VkmdE/v-deo.htmlsi=OjY3I92qBNVPYhtU
Just thought I would mention the reason it has the dual range gear box in the first place. It was done so they could use the Gold Wings drive axle which was on the other side. The transfer case brought drive to the other side and made it a additional selling feature as a 10speed.
Yeah Jon, remember as I've told you, if you're using it in HI-gear, around town and riding it HARD, the clutch won't last too long, "GUARANTTED". It'll be "slipping" soon. Best way , is as you've said, use it as an over drive... > keep it in your thoughts not to HOT ROD it in 1-High! ......
Reminds me of old like Chevy c30 or 50 had your gears and a switch for 2 speed rear end so really when you got up to speed just hit 2 speed rear end button to ease the strain going faster giving it a break . Cool idea for long ride bike doesn't have to labor as hard
never heard of such a system here in NZ or in Aus.. makes me wonder why they did'nt use a bar mounted solenoid switch system instead.. is the dual range gear part of the main shaft or the output shaft.. its novel for sure.. understandable that it never took on
Thanks for that. The mystery is now solved. Love this bike! Could you put this transmission on a CB 750? I love the idea of that top gear, but a 900 is a bit to big for me.
I had a 1982 Dodge Colt manual speed that shift the same way. The stick shift next to it has a overdrive or high range and low range and it shifts just like that but only 4 gears. Must have been something from the 1980s. That Dodge colt was made by Mitsubishi, so another Japanese produce of the 1980s
So I’m thinking about picking one of these up, now that I understand how to use it, what’s the purpose of having one to begin with? When should I shift between high and low range
Low-range is good for pulling out from a stop and up to 50mph or so. Think of the transmission as a six-speed with an additional step that you need to do. No one knows exactly why Honda did this. A six-speed would have been simpler and easier to use. Thankfully, it seems to be relatively reliable. Cheers!
When I got my CB1000C in 1983 I had spent thousands of miles on my 10 speed BICYCLE so it was reflex: run through all 5 rear wheel sprockets on low (forward crank) sprocket then upshift to high sprocket on crank. A 10 speed bicycle has 6 speeds when used this way. The “10 speed” label is misleading in both cases.
I had the 82 Super Sport. How much does that extra shift drop the RPM at highway speed? I loved the bike, but I always felt like it was revving too high on the highway for the size of the engine. It was near perfect. Wish I still had that one.
On the 1982 CB900C, the high range is like an overdrive and significantly lowers the rpm at highway speeds. On the 1980 CB900C, not so much. I don't know what year they made the gearing change. Other upgrades on the 1982 include better brakes. I would love to review a CB900F if I get the chance. Cheers!
Cool demo. What would be the ideal top cruising speed for this bike? I think you mentioned 55 is it's sweet spot but if I wanted to take my CB900c out for a longer cruise, what speed is it most happy with?
Great question! That depends on the year. My 1980 CB900C was geared lower than my 1982. However, you can go at any legal speed you want to without hurting the bike. It's really a matter of what you're comfortable with. Cheers!
@@arlenejnelson OK. It's probably similar to my 1980. Regardless, you can cruise at whatever speed feels comfortable to you. You won't damage the bike. Cheers!
@user-dt5uh7hi5h The high-low range is simply an overdrive. Honda wanted to use the Goldwing's shaft-drive, which was on the opposite side of the bike from the power output of the CB900F engine. That required a transfer case to get the power from one side of the bike to the other. The transfer case made it easy to add the hi/low range. Cheers!
Ish... if (as I often do) you start off in low range and shift into hi range once in fifth it is essentially a 6-speed. I then shift back into low at the next stop. Not 100 percent necessary but it's easier on the clutch pulling out and there's no reason to leave it in low range above 50 mph.
@@jonsmotorcyclerescueandrev3538 It will definitely save your clutch to start off in low range. I cringe when I see some of those modified bikes with a small rear sprocket. They can go 70 MPH in low gear, but their clutches burn very fast. Too bad. I don't understand why people want to have such high first gears.
@@mindlessautomaton2.0 Generally, the high range is for speeds above 45 mph in top gear. However, you can leave the transmission in high range most of the time and just drive it like a 5-speed. Some people use low range for in town and high range for more open roads. Cheers!
Great question Greg! It depends on the year of the CB900C. My 1980 has much shorter final drive gearing than my 1982. I don't know rpm in 5th gear low and high for a certain speed off the top of my head though.
@@jonsmotorcyclerescueandrev3538 Hmmmmm thanks for your reply John 👍 Maybe I will have to buy one to find out 😁 Looking to buy a classic Japanese bike now as I'm over water cooled bikes. For me it's a hassle just to change the sparking plugs. Keep up the good work 👍👍
Correct. Although it technically has ten different forward speeds, in practice, it functions more like a 6-speed. 1-5 and then into high range. In many situations, you don't need to shift back into low range - you can just use it like a 5-speed.
I would have preferred a six speed for ease of use. But, evidently, Honda decided a two-speed transfer case was the way to go. No different than a 10-speed bike. Cheers!
Been rebuilding one of these for two years. Finally getting on it today. Glad to see I don’t need to upshift ten times hahahah
How did the test drive go?

I was almost hoping they were like a ten speed truck😂😂, would be wild, but definitely would only be fun for so long
@@lowxpectations yes. That would have been cool but it’s a five speed with a high low gear. Not a split shift. But still fun.

Hi Doug, the CB900C is a unique design and the transmission is not transferable to any other model. The CB750C chain-drive model was actually quicker.
Had one. I'd use low range around town and high range on the highway.
Right on!
Thanks for the informative video. What was the purpose of the Low and High range back then? thanks
I think it was just to add an overdrive to the 5-speed transmission. Cheers!

I have that same exact bike I love it n
Very cool!
Restoring one now
Very cool. They are smooth-running, neat motorcycles.
hi-low for what ! saves gas crusing at hi speeds ??
That would be one benefit. Less rpm at speed makes for a more relaxed, smoother ride as well.

Never saw anywhere Honda called it a 10 speed. Just high and low range.
@@moparmaker Same concept as a twelve-speed bicycle.
It’s simple , keep in low range when in town , put in high range on open road .

Pretty much. Though you can leave it in high-range or low range and use it like a 5-speed.
