107" Race Engine
$15,000
Championship-Proven. Not Theoretical.
This is the exact engine combination behind our championship-winning race bikes. The one we trust when everything is on the line.
At Daytona, we held 28 seconds of wide-open throttle at 6,800 RPM on 18 psi.
Not a pull. Not a hit. Sustained abuse.
After teardown, the internals still looked untouched.
No drama. No guesswork. Just a combination that holds together when put to the test. If you’re building for boost and actually plan to use it, this is the standard.
