These kits work exceptionally well on Buells. Our superior quality Hurricane forged pistons combined with the the stronger, straighter, lower friction and cooler running cylinders from Axtell combine to give you MORE POWER, with increased reliability and longevity. And best of all, no case boring is required for installation!

But don't let the low price and ease of installation fool you. These kits are capable of making some serious horsepower. Multiple customers have reported over 120 rear wheel horsepower* using these kits, totally streetable. NRHS's resident shop mule and errand runner, a 1999 Buell M2, pulled a whopping 124.8 rwhp!
