COVID-19 Update

As of the close of business Monday March 23rd, 2020, HMF Racing will be temporarily closing manufacturing and operations until May 1st as mandated by the State of Ohio to help slow the spread of the COVID-19 virus. We hope to resume normal work May 2nd, 2020. This is to protect the health and safety of all HMF staff and their families.

All orders that are currently in progress will be put on hold until operations resume. In Stock items are available to ship with negligible delays. New orders may still be placed on our website. Orders placed online will be charged and invoiced the next morning in order to reserve a place in the production queue. Delays in production in addition to the listed production time are possible depending on the volume of orders placed during this closure period.

From the HMF family to you:
Stay safe, stay healthy, and we look forward to helping you with your exhaust and equipment needs in the very near future.

Honda® CBR 250R

The Honda CBR250R HMF Slip-On is available in the Performance (Street) Series.  The slip-on system picks up 15-25% more horse power and torque throughout the power curve, and remains substantially less that the stock exhaust.  The Performance (Street) Series dropped close to 10lbs, added an insanely sick sound, and offers several powder coated exhaust and end cap options for a completely custom look. In combination with the HMF Optimizer Fuel Controller, the result is a pretty slick exhaust system that sounds mean and builds great bottom and top end power.
