The photos below show Jeff Wieand on his 1990 Suzuki VX,
also known as the "VXR". Jeff raced this bike in both the
Washington and Oregon Motorcycle Road Racing Associations
(WMRRA and OMRRA) in the Open GP Twins class. The year he
raced, sometime soon after this bike was made, he placed
117th out of 335. Jeff says he likes to "race anything
that wasn't meant to be raced". Before any modifications
were made to the bike, the dyno said it produced 52 horespower.
After jetting and exhaust modifications, it produced 63
horsepower. While racing he claims to have consistently
wound it up to 10 and 11 thousand RPM. Jeff works at Aurora
Suzuki in Seattle, Washington. Photos are by Phil Tanner.
