Bike: Y2K 650R, HRC breathing kit, Renthal bars, all else stock. The vibration at the bars really gets me. I get numb hands in 15-20 minutes. Definitely more than my old KTM 300 2 smoke, but not nearly as much as my brother's damned Harley Sportster. Questions: 1) Does this seem normal? 2) Has anyone tried any into0vibe insters, like the Fasst Company one reviewd at Off-Road.com?
