.570 Lift Cams for XL's - Only $495!
Are you looking for a low-cost way to add 4-8hp to your late model 1200 with no other changes needed? And not lose any power anywhere in the rpm range?
This is the cam set for you! Using a set of Cycle Shack slip-ons, this cam set showed a strong 4+hp gain over a wide rpm range as compared to the stock "W"
cams in our test bike. Using a Patriot Defender exhaust, the gain came in at over 8 horsepower! In both cases, no bottom end power was lost at all.
Small base circle to simplify installation. Fits 91-up Sportsters and 95-2002 Buells. Bolt-in for 04-up XL1200's only. As with all
HAMMER Cam grinds, these
cams are easy on the valvetrain and quiet in operation.
Available Now!
Check out these dyno results! These were taken on a 2007
XL1200 equipped with an
Air Hammer air cleaner and the exhaust as shown. Tuned with a
Dynojet Powervision. Click for larger view.
