113 Thrasher Upgrade Kit


2007-2016 CVO 110 Models


3 years of continous research and developement has uncovered 10 more foot pounds of rear real torque. We finished our newest updated design 113" Thrasher Kit on a NEW 2014 110" CVO Harley-Davidson Road Glide.

This motorcycle came to us with only 90 horsepower, and we added 50 more!

Now it's WAY more fun to ride! We bored it to 113 cubic inches at 10 to 1 compression ratio. We installed our custom pistons, custom ground cams with oversize valves, and ported the heads to add 50 more rear wheel horsepower!

Not just a "port and polish" job! But, a big change in shape and size to flow enough air to make 140 HP.

We finished with just over 140 RWHP and just over 140 ft. lbs. of torque!
