That’s one combination I haven’t tried yet. Perhaps I should, my area is hilly and twisty toads too

15/35 is just a bit more short than stock (3%). It helps keep the engine in the right revs when it's hilly. And not losting high speed.
With 15/36 you are shorter than me.

I've got the standard gearing on mine. I'm 100kg, and live in hilly Yorkshire....taking into account its a 125, I couldn't ask for any more...I will however want to upgrade the chain at some stage. It stretches like knicker elastic...

I kept mine stock. Going slow is half the fun of these bikes.

I've tried a 14, 16 & 17 front sprocket with a 32, 34, 35 & 36 rear sprocket. In the end I'm back at 15/34 with a Takegawa 181. I have a few hills around me and it holds decent speed.

Thanks for the suggestion. I've ordered one today. I'm just going to chuck the standard one and replace it. My bike has only done 1,000 miles, so not worried about the sprockets...

Just grabbed a G Craft aluminium 34T to go back to stock gearing, original sprocket was way too heavy. Tempted to get some nice chain adjusters whilst I am at it

Just ordered some, and the wheel spacers too based on one of your previous posts, I agree it is a real pain lining everything up to get the back wheel back.

I replaced the front sprocket with a 14T sprocket, kept the stock rear and put on a new DID chain and it runs well, better than stock but its marginal. Speedo gets up to 115-118 kmh at best at the top end and accelerates faster. Still not as quick as my 5 speed 2022 Grom, but then they are different bikes. Gratuitous photo:

New adjusters, spacers and sprocket fitted. Not added it all up, but lots of unsprung weight saved. The Kitaco spacers stayed in place during assembly much better than the stock ones, I think just because they are so much lighter. Just waiting for the sun to return for a test ride.
