This gear set rocks! Review by Ed

This gear set rocks! Harleys typically shift with a clunk. Not this gear set. I sent a new set of close ratio gears to Zippers for their ‘Back Cut Service’. The cost was minimal and with their great reputation I knew it would be done right. I have used Andrews close ratio gears for years in my bikes so I had an idea of what to expect, or so I thought. To say this transmission shifts smooth and reliably would be an understatement. 130 horsepower, full throttle shifts happened with the precision of a fine Swiss watch. Even putzing around town with my wife on the back, the transmission shifts much smoother than most of the sport bikes I have ridden. This has got to be one of the best bang-for-the-buck upgrades I have encountered. From now on, every bike I have will get either a full Zip Rack or have its gears back cut. (Posted on 9/8/2015)
