Works Great On My 2022 Honda Grom
Amazon says it doesn’t work for 2022 Honda groms but it fit perfectly on mine. I have to add though, I also have a 31t aftermarket rear sprocket (as opposed to the 38t stock on 2022) so the 13t front with the 31t rear (2.3846) gives me a little higher top speed than the 15t/38t (2.5333) stock setup. But because I reduced the radius and mass of the rear sprocket and shortened my chain by 4 links it reduces the total rotational mass of the drivetrain and makes torque/power available to the wheels for acceleration that was previously being lost to just spinning up the drivetrain. It’s not much but it’s something. When doing this on some bikes can sometime give back 0.5-1hp and the Honda grom only has 9 to begin with on a good day that’s a 5-10% increase. 🤷‍♂️ Either way it saves on gas. But I highly suggest going this route. Even if you want to stay at stock gear ratio you can still do 13t/33t (2.5384) and this will reduce the overall rotational mass to give back a little that was previously being lost.It’s a gear though. As long as it fits properly and is made of quality alloy what more do you need?

Wake Up Your Grom!!!
Installed on 2015 grom. Complete game changer. I'm 230lbs, got stock up to 62mph downhill, full tuck. With this 13t sprocket it cruises at 60-64 right under redline with no issues. Every gear seems more peppy and 4th doesn't seem like it's asleep anymore. Best mod you can do for the cheapest of prices!

Loose fit
Machined poorly and fits loose on splines of countershaft. Countershaft is not worn. Went back to OEM sprocket and fit is snug and secure.
