Polaris Sportsman 500 EFI fuel injected models w/EBS.

Oversized tires only. 472-DBW500EF: A cost-effective kit designed to help restore some of the acceleration lost from installing bigger tires. This new 500 fuel injected model is indeed somewhat different than previous 500 HO models. The use of oversized tires, as usual, did show a significant loss of performance, speed, and acceleration. This kit will help bring your bike back to life after installing those bigger, heavier tires, and also improve belt grip and throttle response. Top speed on this model is slower with big tires than with stock tires, and it will remain the same (within 1-2 mph) with this kit installed. This kit is NOT for use with stock tires at low elevations.
