TB Performance Camshaft for 2014-2021 Honda Grom & Honda Monkey 125
A great, new performance camshaft designed for the Honda Grom. This can be used on either a stock bore motor or with the 186cc bore kit we offer!
This is a NEW CAMSHAFT , NOT a RE-GRIND !!
This cam has similar performance upgrade specifications to the DCR R2 cam but is less then a 1/4 of the price.
Note: Factory decompression mechanism will not work with this aftermarket camshaft.

Great performance bump for the price. Paired with Mtake, TB Parts exhaust, and DHM reflash…this thing now keeps up with traffic….stock it would run 45-50, now does 55-60 no problem. It likes to rev now! lol

Does it fit a 2024
Kevin Estep –
Yes. Use the drop down menu at the top of the site. Put your make / model / year in, and it will only display parts that fit your bike.

This is the sickest update you can do for your grom short of a bore kit. Before, my OG was doing about 52 miles per hour upright and about 59 in a tuck on level ground (around 6500ft asl in Colorado). I’m not a big guy by any means, 5’9/165lbs so that was sort of a sad top speed. With this cam, exhaust, and koso filter/intake tube (and ecu flash) it will do 65 all day on level ground and 70mph in a tuck on flat ground. It actually has “passing power” as well to drop a gear and get around slow cars. Less than $300 total for all my mods and the thing is a completely different bike. Plenty of videos on YouTube showing you how to do this install safely, and easily.

This cam completely changed the way the monkey rides. It really wakes it up from mid to high range. And honestly just gives it more throttle response. I must have with this cam is the ECM flash. Can’t recommend this pair enough. My monkey feels like a completely different motorcycle now

Excellent cam for the price, easy install. I would highly recommend if someone’s looking for mid to high RPMs and a stock bike great addition even if you’re running a flat top piston. Would recommend some type of fuel controller though

Great cam, bottom end lose some but 5-6k it wakes the bike up and keeps pulling.

Excellent cam. The bike really woke up after installing this cam. The lack of decompression mechanism did not alter start-up either. Defiantly recommend this cam to anyone looking for a boost of power.

huge improvement for a stock bike, even with no fuel programmer, just putting 93 octane and riding it with no other mod it was running 65 mph on flat ground avg 55-58.. not bad for no tuning.. will retune difflently can tell the power has shift higher up in rpm and this would be a cam i would suggest for stunter
