Sprockets and what size to go for

[Felix]

Hey,

Currently buying new sprockets and chain and wondering what sprocket sizes I should get, I've currently ordered a - 1 on the front and leaving the rear standard, will I notice much of an acceleration difference and difference in the bike or should I go +2 on the rear too? Thanks

Only asking cause it's a lot of money and don't want to be disappointed

Should be fine.
Just make sure the chain has the right link count for your year.

Do you think a +2 would be too much? I want a lot of acceleration

Gearing

As a rule just remember the following when making any changes to gear ratios:

Gearing a bike up to produce higher top speed with less acceleration is done using a larger front sprocket or a smaller rear sprocket.

Gearing a bike down giving it more acceleration with lower top speed is done using a smaller front sprocket or a larger rear sprocket.

Generally speaking changing one tooth on the front sprocket has a significantly larger effect on the gearing than changing one tooth on the rear sprocket. To make only a small change in gearing it is therefore necessary to change the rear sprocket size by one tooth, as changing the front sprocket makes a far larger difference in gearing.

You may not always have to reduce the number of links when altering gear ratios but bear in mind a reduction in chain length may positively, or negatively, alter wheelbase. For the 2015-on model retaining a longer wheelbase is preferential.

is the bike for track or just general road use?

-1/0 F/R. Start there. It's not the traffic light GP which matters it's drive out of corners.
