Z1B sprocket sizes

#1 PostAuthor: kwaka » Thu Dec 17, 2009 3:37 am

Hi all, can anyone tell me what the factory front and rear sprocket sizes ( ie number of teeth ) were on the Z1B's. I'm looking at reducing my highway RPM for cruising.
Cheers

Thanks Steven, I havn't taken the sproket cover off to count the front sprocket, but the rear has 33T and i find i'm always looking for an extra gear when highway cruising. I suppose they were really built for off the mark performance rather than highway cruising.

Mr Cooke correct!

Z1 + Z1A + Z1B = 15t front and 35t rear

Z900A4 = 15t front and 33t rear
(except the Italian Z900A4 which kept to the 35 rear)
