WR Gear Ratios

January 13th, 2010 | Drive, WR250R

Another WR owner on ADVrider.com, Chadx, created this gearing ratio for the WR so I wanted to repost this information before it gets lost in the thread!

Stock gearing is 13T Front / 43T Rear sprockets with Trailwing rear tire. The ratio with the taller D606 rear tire assumes a 5% increase.
