this maybe of help regarding grearing:
http://ducatisportingclub.com/contro...d.php?tid=6030 Shazaam has posted some pretty detailed posts on the subject of chains, sprockets and gearing.
Bought my chain Tsubaki chain and 14T front sprocket from B&C express, really good service and the chain looks great , no trouble with it, bullet proof too...apparently, looks it.
Agree that chainging the original gearing really does make a substantial difference to acceleration. Went for 15 40 just now may well go 14 on the front to see what difference it makes.
