Yamaha FZR 400 R/RR/SP Ignition Rotor and adjustable Pick-up plate
More BHP, quicker steering, quicker revving 1.5kg off the crank!

Now to fit all models!
But you must tell us what Model your bike is.

This has to be amongst the very first mods you do for the track after taking your mirrors off - more bhp, quicker acceleration, quicker & easier direction changes, weight saving and all for the cost of a pair of tyres!
Total weight saving 2.5KG!

This computer-designed, CNC-machined rotor and pickup plate is machined from HE30 (plate)and EN1A (rotor) alloys.

Coated in zinc passivate, the rotor is dynamically balanced, and weighs only 180g compared to the standard flywheel that weighs 1.6Kg.  That's like having one and a half kilos removed from your crank allowing for much improved throttle response and quicker acceleration and better engine braking.  
Not only that but as you can see from the comparison photographs most of the weight of our rotor is in the hub near the centre of the crank where it will only be doing around 30mph at 14000rpm - the original rotor holds most of its weight 60mm from the centre of the crank so it's moving at around 200mph.
It's easy to see how much difference this will make to the way your engine spins up.

Gyroscopic forces from the engine are also reduced making the bike easier to tip in and change angle.

The pickup plate is indexed in 1° increments so that the ignition timing can be manually adjusted from std to 8°advance. 

By reducing the flywheel inertia to a negligible amount, and finding the optimum ignition advance for your particular engine, a gain of between 3 to 5 Bhp can be obtained. Obviously, as the generator is removed, either a fully charged battery or a race generator (also available) is required. 

We have never seen an FZR want less than 4 o advance over standard with a kit ignition, however people have suggested that 2 oretarded works better. Ours run between 7o & 5 o.

Note: Standard Bar End Weights Make Good Flywheel Pullers.

The number of mods we do for these bikes is simply too long to list - check out our other ebay listings if you like (we don't eBay much), check out our website and then even better give us a call.  Engines race prepped, oilways drilled, pocketing pistons, bigger valves, carbon fairings and seats, lightweight parts, race generator...........on and on.
