As requested.
My rear axle is an LT500 made by TEAM. Rear brake rotor and sprockets are LT500 pattern bolted to oem LT500 sprocket and brake hubs. My axle hubs are Yamaha bolt pattern by TEAM as well.
I purchased the caliper through my local Yamaha shop. Its off of a Yamaha FJ1200 street bike. I purchased the axle, hubs, rotor, sprockets and custom brake stay through Duncan Racing.
The brake stay was sourced through Duncan's affiliate, ATV World in Europe. These are replica parts to the last PDV Laegers Banshee that Duncan/ATV World raced in about 2007.
I purchased two rotors and two brake stays so that I had spares in case of damage and availability with custom parts. I'm not sure if my brake rotor matches oem LT500 on the O.D. or not. It for sure is LT500 bolt pattern.
Rear end is built like a truck and stops like it has air brakes.
