Jul 26, 2021 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... Joined May 25, 2013 · 73 Posts

Jul 26, 2021 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. 2020 Honda Monkey

Can we get a clutch cover with water pump, a water cooled head, and a small snail then? Joined May 25, 2013 · 73 Posts

Jul 26, 2021 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. Joined Mar 22, 2021 · 85 Posts
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.

Longer stroke, I wonder if it will limit RPMs.

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.

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.
