SLR650 sprocket sizes

[Oscarthecat]

Can anyone tell me the standard number of teeth on front and rear sprockets for a 1998 SLR650, please? My GF's new acquisition has been geared down with a Renthal sprocket, which is fine on the country lanes but no so hot on the main road

Regards
Richard

hi mate, standard sizes are front 14 and rear 43. i changed my rear to a 45 tooth. it now will do 40mph in 5th gear without trying to vibrate everything loose...........on the standard size rear it would only do 50 in top without labouring
