New CycleRama High Intensity CR-575 Cams

Postby spmullen on Tue Sep 29, 2009 7:59 am

10-time Brute Horsepower Shoot-Out winner CycleRama is proud to release its new High Intensity 575 cams. Designed especially for 2007 and later Twin Cam engines, although equally effective in earlier models, they utilize specially designed proprietary ramps to increase flow velocity and maximize cylinder fill. As a result, they intensify low and midrange performance with no compromise at high rpm. The High Intensity 575's are available in chain and gear-drive versions, and work their magic in stock engines as well as those with ported heads and displacement increases. Minimal valvetrain noise makes them an ideal choice for baggers as well as Dynas and Softails. For more information, contact CycleRama at 727-546-0889 or

Nightrider Notes:
As an example, a test dyno run for the CycleRama High Intensity CR-575 in a stock TC95 FLHX w/slip-ons produced 86HP at 5500 RPM and 103 Torque at 3500 RPM. The torque was above 100 from 2700-3900 RPMs and above 90 from 2300 to 4900 RPMs.

CycleRama does many designer cams, but the CR-575 is one of their best. This bolt-in cam is very effective for the 2007 and later bikes with the 6 speed transmissions with their very tall gearing. The torque of this cam is centered around the highway cruising RPMs of these bikes. Riders will find this cam produces considerably much more power than the 103 big bore upgrade. If you are considering a single upgrade to your 2007 and later bike, this one should be at the top of your list.
