Gearing ??

Has anyone on here changed the gearing on their Cat at all?

To be honest the top end is more than enough for me but I do like my twisties and acceleration so I was thinking of re gearing to lose some top end but gain some mid range acceleration.

Anyone have any advise or know of a good resource for investigating?

Yes you can go down one tooth on the front sprocket & one up at the rear & replace the chain.

Yep, I put one down on the front and two up on the rear when I did my last chain and sprocket when I had the cat.

Worked well, couldn't tell you what got lost off the top end I as only went there when I was young and daft(er).

The front end came up a treat if you over egged it, I found it nicer to ride around town in traffic too.

From what I remember, with the standard gearing, around thirty (or another common speed) seemed bang on between two of the gears, when I changed the sprockets it wasn't an issue any more

Fantastic chaps, just the advice I was after. I find that 30mph chain slap annoying too. You either seem to be chugging or screaming.

One other question then, what's the normal gearing front and rear (IE teeth count) so I can work out what to get.

Google and ebay say that lots of 'standard' chain and sprocket kits are 15front / 47rear

I'm not home though so can't check my Haynes Book of Lies but it sounds right
