Ivan Hoey of Australia has 1 set of these gears left in stock, he is looking at getting another batch of 10 made soon if enough interest is shown.
They are an exact copy of the Halco primary gears, originally designed for sidecarcross. (approx. 20% increased clutch speed)
These primary gears make gear changes much smoother, reduce clutch slip and most importantly by spinning the clutch and gearbox faster they reduce the damaging torque load of big bore XS. You can simply just gear it back down at the chain end, and maintain your original gearing. Or for the road racers, you can go faster than ever before!
Easy to fit, clutch basket will have to be disassembled and some machining is required. They come with a full instruction sheet anyway.
Hopefully they will still be around $700AUD (+postage) mark, just waiting to hear back from Ivan on the price. I will post a new price if there is one.
PM me if you are interested, or better still, email Ivan direct: ltr.management@bigpond.com
