Aggressive Mid-to-Top End Power Gains

Transform your engine's personality with the Hot Cams Stage 2 Intake Camshaft. Available at Moto-House MX, the 2251-2IN is the go-to choice for riders who want their 400cc machine to pull harder and longer in the upper RPM ranges. Whether you are building a dedicated track bike or a high-performance street supermoto, this Stage 2 cam delivers a dyno-proven 5% to 10% power increase, specifically targeting the mid-range and top-end "over-rev" that factory cams lack.

Precision is paramount in high-performance valvetrains. This intake cam is CNC machined from 8620 billet, case-hardened steel, ensuring an exact lobe profile that resists wear even under extreme racing conditions. Featuring Hot Cams' Improved Throttle Design (ITR) technology, this cam doesn't just add peak horsepower—it sharpens throttle response throughout the entire RPM range. Engineered in the USA using state-of-the-art software, the 2251-2IN provides a professional-grade power boost while maintaining the reliability Hot Cams is known for.

Frequently Asked Questions

A: No, this cam is designed to work with your stock timing gears and provides the 107.5° lobe centerline automatically when timed to factory marks.
