HMF Exhaust Release – Yamaha WR 250R

BROOKPARK, OH, June 24, 2009 – (Motor Sports Newswire) – HMF Dirt Series: The HMF Dirt Series delivers the most horsepower & torque gain per dollar of any other after market exhaust system. It was specifically designed to deliver maximum power gain throughout the RPM range. If you need to run quiet from time to time, the Dirt Series accepts the optional HMF Quiet Core.
HMF-Dyno Chart
The WR250R is for riders who ride off-road more than on. Its sibling, the supermoto-inspired WR250X, is for riders who spend more time on pavement.  Each model features a 250cc liquid-cooled, DOHC engine with two titanium intake valves and two steel exhausts, forged piston and plated cylinder for outstanding durability.  When we installed the HMF Slip on to the bike, we were able to pick up 3HP on the dyno.
