In the 15 years HRH/HRB/BIKE-Works has been around, a lot of good people have done their absolute best to bring the readers informative performance enhancements for their motorcycles. This being the last issue, it's only right that we take a look back over the years at some of the highlights from all the bloody knuckles, dyno runs, and general fun we've had. Enjoy.
Note: Unless otherwise noted, all dyno data is based on averages between 1,500 and 6,000 rpm.
