I'm looking for sprocket sizes ( No. of teeth ) that the American desert racers used in the '70s for their old 400/450 WR's.
As I intend using my '75 WR400 on the road, I'd like to gear it up a bit. Some years back I rode a 360 Montesa, ex- US desert racer, belonging to Ron Merrick......it took some winding out but that thing would do 130 MPH....and very scary
