2022 honda grom big bore kit

Just curious, no rush. But I'm interested in gaining 2-4 extra whp (for 10-12 whp total) with a modest 150-160cc kit, whenever they become available. Well, these were already shipping in Asia for a while, yes? Maybe there's something already, but I wouldn't even know where to look.

It may never happen, at least in the capacity of prior models. When Honda changed the bore and stroke, the cylinder studs got substantially closer together, limiting what can be done in terms of big bores...

When they do things like that, sometimes it means they don't want to compete with themselves, I wonder if a hopped up Grom is forthcoming from Honda.

Can we get a clutch cover with water pump, a water cooled head, and a small snail then?

I was only hoping for something modest like 150 or 155, easy small gains of a couple whp.

What were the biggest bore kits previously? I see 170, 183, 186, 200, and 235 with a quick search.

I wish it looked more promising. Aftermarket intakes show gains of only 1/4 to 1/2 HP. That's less than on the SF. Maybe an ECU reflash, cam change, and hi comp piston may yield better results, since the engine is probably really leaned out for emissions. That gearing is definitely making them slightly faster in the 0-45 run.

Well my plan was to let things develop for a year before jumping into modding. I wouldn't want to touch anything if there's not a clear path to a solid +2.0 whp.

on my 2022 : just purchased a Yoshi rst-9 and front 14t sprocket.

next on my hit list is aracer.

then dhm h/c piston and cam

finally a race head from dhm

Headwork will be the way. Plus rpm.

Longer stroke, I wonder if it will limit RPMs.

Didn't somebody say the bore to stroke ratio was unfavorable already for higher rpm?

Like Honda is trying to make the bikes unmodifiable.

I was thinking the same too. It's cannibalizing their sales in other markets, so I think this is their way of boosting their other sales. (Like the H'ness, CB125r)

just installed my Yoshie fender elelimator kit on my 2022. its really good looking

Except Honda (or anyone else) doesn't offer 15-19hp 125 bikes in the US market.

We've got confirmation from Kitaco and Takegawa that they are working BBK, Cranks, Cams, Piston, and much much more for the New Gen 3 Grom RR.
As soon as they have more information, and pricing , we will post it up on our website, Immediately.
Just hang in there.

monkey father make a kit : 149cc bore; race head with big valves and costume ground cam
also comes with ported intake manifold and throttle body.

will need a added oil cooler available at weblike

also installing moto bro 60% SPRINGS and billet clutch pressure plate

Have a look at dhm on facebook

they just did a monkey

looks about perfect

Check out Team Green's updated z125pro. I think they're claiming ~ 15 ponies.

I see 9.5 horsepower listed
