ASR Motorsports has started using Microlon now, and let my say, Microlon is incredible . Building 50 to 450 cc racing motors, we are always looking for ways to reduce friction. There was a measurable increase in horse power after using Microlon. Our 50 cc motors dyno at 14hp after assembling with Micronlon. We gained 1.4 HP! That is incredible considering the small displacement.
