sprocket sizes

bikermike182 · Aug 3, 2014

Hi guys along with changing my tyres this week I'm also changing the sprockets , current sizes are 16 and 42 when I got the bike a new chain was put on by the dealership. I want to change the sprockets for more torque but want to keep the chain what size is the right size to get so I can do this 15,44 ?? Any help would be great thanks.

15/44 should work

:no
For a Gen2,the best combo is 15/42.
The standard chain is too short to fit a 44t rear sprocket,...an extra link will be required.

Why would you be fitting a standard chain though ? Surely if you're investing in nice new sprockets you're buying a decent DiD type chain etc.

It was a typo,...i meant standard length chain,....anyroadup,the OP has had a new chain fitted by the dealer,...did you not read that?

15/42 is the best it suits the bike perfectly

Yeah...me too.
The axle is fairly snug in it's slot, but it IS do-able.
Has the advantage of shortening the wheelbase a bit too, so in theory, it should turn in easier.
But still waiting for V Rossi to confirm this for me though.
Mine used to top out at 164mph....now it's more like 145ish.
It rips through the gears like a scalded cat....and a little less jugga-jugga around town and in slow moving traffic.
No noticeable difference in fuel consumption.
All in all....recommended.

Who needs 164 mph anyway?

It's all about acceleration and handling

Let me know if it turns in easier at 145mph

Tifa · Feb 2, 2015

can't guarantee it turns in easier....but I can guarantee it's easier to pull up out of a ditch. :Oo

For the road. 15T with 44T is a hoot. Very quick through the gears. Who cares about top speed?
