Crownwheel, 47 tooth, 4/5, MB plate, lightened
We were so disappointed with the standard of available sprockets that we decided to have our own made.
They are designed to be used with the more reliable Li, Sx, Tv, Li-S type clutch needle bearings rather than the GP style bush.
Each crownwheel is supplied with 2 clutch needle bearings.
Our crownwheels are lightened as much as you can without suffering any issues. The bearing area is precisioned machined to give no rock or lift in the crownwheel making them more reliable for chain wear.
This sprocket can work with 4 / 5 plates or 6 plate internal type clutch conversions and has 47 teeth.

- Fed up of poor inferior products we designed our own.
- What ever product was used extra machining and grinding was required.
- The precision of the crown wheel is very important for chain and clutch life.
- Always dial gauge the crown wheel with the front drive sprocket to improve chain life.
- Always check sprocket lift and shim up to suit.
- Always fit new end plate bearings and clutch needle bearings.
- Make sure both clutch friction, steel, pressure plate fit and slide up and down freely.
- Always soak clutch plates in ST90 for 24 hours before fitting.
- Steel tabs on top and bottom friction plate can be bend 20 degrees to aid the clutch.
- Always use a clutch holding tool to tighten the clutch nut.

- Made in the UK using modern steels, lightened and precision CNC machined.
