Five-time world champion Jeffrey Herlings put on another absolute clinic at the MXGP of Flanders in Lommel, Belgium sweeping both motos (the fist by 45 second to his closest competitor) to claim a dominant overall victory aboard his Honda HRC PETRONAS CRF450RW. The Dutchman pulled back-to-back holeshots and charged through the notoriously brutal Belgian sand to capture his record 120th career Grand Prix win. With another maximum 50-point sweep in the books, "The Bullet" stretched his championship lead to 104 points—proving that his high-stakes move to Big Red is certainly paying high-speed dividends.

Designed to boost horsepower and trim ounces, it delivers a crisp, throaty exhaust note guaranteed to put a smile under your helmet before you even drop the clutch.
Yoshimura R&D of America gives the modest Honda XR150L a much-needed vocal upgrade with our easy-to-install RS-2 Slip-on exhaust.
