Converting the Grom to 428 Chain and 14T Sprocket Setup | 2023 Grom Build Part 11

- I've always heard that a 14T front sprocket on a Honda Grom actually let's it hit a higher top speed, despite conventional wisdom. So we're trying it and going to a 14T front, 38T rear, and doing to 428 pitch sealed chain instead of the stock 420 plain chain.
Oh, and it's gold! I can't help it. I might have a problem.

420 oem chain stretches out completely within the first year of riding. On my first Grom I had to adjust it every week. Got a better 420 chain the year after, it was night and day.
🤘🤘 great video
Dude, hype for the video. Love your turn signal mod, resisting with all my heart from copying it. If that company had break ones for the rear I'll cave in a heartbeat.
Thank God our Groms have a cush drive to dampen that massive amount of torque the 125 puts out.
Hey bro I went went the same setup but 2 extra links on the chain and 37t sprocket and it’s not fitting right and rolling right
14 t 428 es el piñón de arrastre y que número pones al plato deja los mismo dientes o lo baja para mas velocidad??
Kudos for going 428, Mine is still sitting in the box, I have a 420 to wear out first. ....Let me know how you like it.
Suck’s everything is sold out 😢. My stock chain is stretched and not much more adjustment. Could I remove a link or two until they get them back in stock?
Spencer. Thanks for sharing your videos. It has been a year since this video, and I would love to hear your thoughts now. Are you still happy with the 428 conversion? When you need to replace your chain do you think you will you keep it, or will you go back to a 420, or maybe a non-x-ring chain?? I am planning on some long distance trips on my Grom and trying to sort out a few details that will help with power in the mountains and not kill fuel economy. Thanks for your thoughts!
Did you go longer on the chain as well or no
What are the advantages the after-market adjusters?
Hello, i went with the same configuration, but after installing everything ive been having noise, somewhat grinding by the front sprocket area when coasting and on 2nd to the 5th gear. Any opinion and advise what might be causing the noise?
Does this mean now that your top end speed will increase, will your speed low in the gears decrease the torque & speed ?
where can i buy that xring chain? any link?
Yo was your front sprocket still a little wiggly when tightened?
Silly question but can I bump to a 428 without swapping the sprockets?
Just ordered a 428 kit for my ‘23 as well from Sprocket Center after chatting with them. He said even on a stock grom it’s worth the upgrade. I also went 14T/38T. How do you like it now that you’ve ridden it?
It seems like you doing backwards ;o) Moto3 bikes with 60HP are using smaller and lighter 415 chain then your grom. 428 seems like an overkill for 10hp bike. I would also check gps speed for top speed as your speedo will be off, subjectively showing higher speed numbers. With 14T you may gain on acceleration but for top speed i think lower resistance, stock size 15T will be a better option, Enjoy your 5th gear!
