The SURPRISING RESULTS of a Slip On exhaust on our new 2025 R3!

These bikes are SO LEAN from the factory that even just installing a slip on exhaust systems throws the combustion AFR into the dangerously-lean territory! Our custom ECU mapping resolves that, and much more. Our Mail In ECU Flashing Service is available for these bikes at 2WDW.com for $299.99. If you have any questions, please email us at [email protected].
