Changing ratios - Rear Sprockets
Hi all Im thinking of changing the sprockets im running and thought id ask the question to see what the masses are running.
The Duke is fitted with a DID ERV 520 chain, Renthal 15T front and 38T rear with Renthal sprocket carrier.
The chain is mint and as its due for a service down at JHP in January, fancied changing the cogs. Bearing in mind ive heard if you go up too much you have to change the chain, (DONT WANT TO DO THAT)
In France this year with this set up I had 170mph showing on the clock. Im not bothered about the top end as in this country id end up inside.
