Hey Guy's, Was just curiouse am in the process of sorting some sprockets and was just wondering, If going -1 on the front is the same as going +3 on the rear....Does it make any difference to performance to do one or the other????
The advantage of going -1 on the front is that I can use the chain I have

.
Cheers Dave....

Stock is 16/43.....Looking at either 15/43 or 16/46....But may need a new chain to go up at the rear

get a calculator and do rear procket divided by front sprocket and u have the ratio
if u did 46/15 you'd be on the back wheel everywhere

go one down on the front, and get the 43 toothed bling hardened annondised alloy rear which are lighter also and look cooler.
oh n you should be able to get it on the back wheel with standard gearing, my honda does

just slam it down a gear, and jerk handlebars back and clutch her up
although if you can do it with just power its safer and easier to handle

HTFU Disco it's doable on the standard gearing. Bring the bike around and I wil show you
drop down one on the front anyway. it will make the bike feel alot more positive under power
