QuoteI was in the same boat abot two years ago when I first went from the stock 130/70 rear tire to a 130/90 which effectiavly drops 1000 rpms for each gear. for me it was easier to find tires in taller sizes than a new sprocket. instead of going to a 18 tooth sprocket you may want to try going to a 80 series rear tire.
That means that it is a very very effectiv way to choose a new rear tyre - which
effectively drops 1000 rpms for each gear. Well - how does this big tyre change the bike - is it more difficult to ride such a tyre!?

ratio 130 / 90 = 1,4444444
130 / 70 = 1,85714286
