Close up of dry clutch assembly.
Combines an efficient oil pump with a dry clutch. The rotary oil pump is driven by a gear behind the crankshaft primary gear which gives a superior flow rate to that of the original plunger pump.
The Dry Clutch has fibre coated friction plates and steel drivingplates. The Primary Gear and Clutch Drum are supported on needle roller and ballrace bearings for a low friction drive. The Clutch cover being an aluminum casting, adnodised to give the appearance of electron.

Honda 450 true close ratio 5-speed - We have the last of the Nova CR racing 5-speed transmissions.
Honda 450 close ratio 6-speed - Team Hansen Honda collaborated with Graham Dyson of Nova Transmissions to develop the world's first 6-speed close ratio racing transmission for the Honda CB450. We are the exclusive U.S. distributor for this product.
Full Six Speed Close Ration Gear Set comprising both input and output shafts and all gears, 3 selector forks, selector drum, indexing block, and neutral indexing roller. Supplied fully assembled ready for installation.

All engagement dogs are undercut and have three dogs to promote positive and rapid engagement.

We have dispensed with the standard circlip retaining the Clutch Centre and manufactured the input shaft with a screw thread. The gearboxes are supplied with the necessary washer and lock nut together with the Clutch Pressure Plate pusher. The only modification required to fit this gearbox using the standard wet clutch is to provide sufficient clearance in the centre of the Clutch Hub for spanner to fit the nut.

Should you in the future decide to fit the Dry Clutch this arrangement will be already in place and not involve any more additional expense.

Tank Decal - The original decals used on the Hansen CR-450's in 1967 were not included in the shipment of motorcycles to Bob's shop. So, he used the decals from a 90cc step thru kit offered by Honda. My decals are only .008 thick which makes them the thinest you'll find available anywhere. Instead of the heavy mylar offered elsewhere, which makes it difficult to cover with paint, these decals can be easily applied on the tank with or without clear coating. They're so thin, you can barely tell that they're decals.

Price: $28.00 per pair (free shipping)
