Honda CB750 Lower End


Cycle X Better Than OEM Primary Chain Tensioners

As most of you know Honda discontinued and are out of primary chain tensioners for Honda CB750 SOHC (69-78').
Good we can improve them.
We noticed this would be a problem early on and decided to take action. After a few months of research and development we came up with the perfect solution!
Introducing remanufactured OEM tensioners with our special material for the wheels unaffected by heat and will never wear. This is the same material used on our cam chain tensioners and manual primary chain tensioners. Guaranteed for life.

Cycle X Clutches

Lock Up Clutch Assembly  


 New!  Lock Up Clutch  ( 33% lighter )

Some high horsepower Honda's have a tendency to have clutch slippage in high gear.
Most people will install heavy duty springs to overcome this problem, but creating a stiff feel at the lever.
Heavy springs can make your clutch lose its nice, easy operation when leaving the stop and go light. 

Our lock up clutch will increase pressure with RPM ( guaranteed not to slip )
Lock up clutch kit includes :
Billet spacer plate.
Clutch plates.
( 2 ) Oil seals
Lock-up Pressure Plate. ( 33 % lighter )
(2) Gaskets.
(2) Dowell pins.
Extended clutch adjustor. 
Oh yeah, looks cool.

Cycle X Lightened Alternator Package:

Quote: "Those Honda CB750s are really smooth running."
Quote: "I installed an RC engineering lightened rotor for more rev capability ( love that old performance stuff )"

Well, the second photo shows an early ( 6.9 lbs), late ( 5.7 lbs ) and a Cycle X alternator ( 4.66 lbs )

Before we go any further !!!!

Our balancer shows stock Honda CB750 crankshafts and alternator rotors out of balance. This may be due to mass production or just 70s technology.

So, let's say your crankshaft is out of balance 6 grams ( we have seen this ) . Let's say your rotor is out of balance 5 grams ( we have seen that also )
Lets say you reassemble your motor with heavy side of the crankshaft and heavy side of the rotor on the same side. ( do the math ).............Smooth running and happy ?

The third photo shows an old RC lightened rotor that is out of balance 6.846 grams ( more math )

Introducing the Cycle X Lightened Alternator package:
- Lightened and balanced to perfection rotor.
- Puller to remove you old, heavy and out of balance rotor
- Oil seal for your starter ring gear.
- Cycle X exclusive no leak gasket ( No sealer needed )

Note: The Cycle X balancer measures inch grams, making our crankshafts and rotors the best in the industry and history.

40 plus years later, you now say, "Those Honda CB750s are really smooth running."

For 1969-78 Only

Note: Exchange basis only (Send yours and we'll send you a lightened alternator)
