 Featured Product #3:


New Six Spring Honda CB750 SOHC Clutch System for High Horsepower Applications.
Includes new Billet lifter plate.

The six spring, seven friction and steel clutch system is a bolt-in upgrade for your Honda CB750 SOHC hot rod. These systems have been around for years and are generally used on 90+ horsepower Hondas or synthetic oiled race bikes. The frictions, steels, and springs are interchangeable with all CB750 SOHC models up to 1978.

Cycle X 6 spring clutch system benefits:
The six springs give a clutch tuner more pressure options. For example: 3 weak springs, 3 strong springs, 6 weak or 6 strong springs.
8 friction plate design will handle the most demanding horsepower applications without using ridiculous spring pressures used on 4 spring designs.
New steels are included to insure the system will work perfectly.
New mild pressure springs are generally perfect for most applications.

Kit includes:
6 spring Billet lifter plate with new bearing.
Inner clutch hub "modified".
Outer steel clutch hub "modified".
 bolts, gasket and oil seals.
New clutch springs.
New clutch fibers. (EBC brand)
 Honda OEM clutch steels.
New lock tab.
This kit also includes a modified clutch cover because the 6 spring clutch system is 6mm wider than stock.
6 springs. 8 frictions.

Note: This kit consists of new, modified and refurbished Honda parts.
Consider the easy pull clutch cable for the best Honda cb750 clutch system in the world.

"I just want to thank Ken at Cycle X for all his assistance with my clutch problems. I had a Barnett extra plate clutch, and although it didn't slip,
it had jerky and noisy engagement. I tried a different clutch and that engaged smoothly and quietly but slipped in the upper gears.
X 6 spring conversion cured all these problems. I've attached some pictures of my bike. Thank you."

Camshafts for sale.
Most of these camshafts are new and were generally used for checking valve sinking, lifts, durations, valve to valve,
 imperfect rocker arm ratios, lobe centers and such.
They do not come in the original boxes so they are considered almost new.
All camshafts will include refurbished/slotted cam chain sprockets and shouldered bolts for degreeing.
