Re: does anybody have Thrust stage 2 520 conversion?
I'm going to ask the obvious question, what makes thier 520 conversion a stage 2?
A 520 conversion is taking your stock steel 525 or 530 sprockets and replacing them with 520 sprockets. The front generally you keep as steel and the rear you generally replace with Aluminum. The 520 is thinner than the 525 or 530 and therefore the chain is also, making them both lighter. Aluminum is lighter than steel so you drop more weight on the rear spocket. This lighting reduces unsprung weight on the motorcycle, unsprung weight makes a big difference when steering a motorcycle and it can allow the wheel to spin up quicker.
520 sprockets are pretty much standard track issue with tons of sizes available, you would have trouble finding an unusual 525 or 530 spocket.
What would make this a stage 2? Unless that is the product name and not a description, someone is pulling your leg. If you don't believe me, I have a whole box of powerbands laying around that I will sell you cheap.
