Description
GPFAX Sintered Road Race Brake Pads are for RACE ONLY use. This is a blend of brake pad that has higher friction and far better grip than any other brake product on the market.
GPFAX Sintered Road Race Brake Pads have by far the highest known friction with a measurement between 0.6 and 0.7 and deliver the most amazing brake effect. Because of this factor, they are unsuitable for street use or for road tyres.
Zero brake fade is guaranteed and the heat stability of these brake pads is perfect leaving the racer with high confidence and a product that can be used over numerous races.
GPFAX Sintered Road Race brake pads are a closed circuit use pad only and street/highway riding with this material is highly inadvisable and dangerous. Such high friction levels as delivered by these pads are for ideal track conditions with race tyres or slicks on prepared asphalt surfaces and NOT for use with highway tires or on the highway. This material is not ECE R 90 approved nor TUV tested with a German ABE and use on the highway is therefore illegal in many countries.
FEATURES
- Highest known friction level
- NOT TUV tested or ECE R 90 street legal
- Lifetime performance guarantee
NOTE: For racetrack use ONLY, not intended for street use.

Vehicle Information
KTM 450 SMR Dirt Bike (2004-2026)
The KTM 450 SMR is a dedicated supermoto racing machine, having undergone continuous development from 2004 to 2026. It is primarily offered as a single, race-ready model rather than in multiple trims. It is powered by a single-cylinder, four-stroke engine, with a displacement ranging from 449 cc to 449.9 cc. Over the years, the 450 SMR has seen several major evolutions. Early models (2004-2007) utilized the carbureted RFS engine. In 2008, the XC4 engine platform and a new chassis were introduced. A significant redesign in 2012 brought electronic fuel injection (EFI) and an updated chassis. After an absence, it returned to North America in 2021, based on the 450 SX-F platform, featuring a compact SOHC engine and supermoto-specific components. Engine, chassis, and fork refinements followed in 2023 and 2025, while the 2026 model focused on noise reduction and connectivity. Q : How can I ensure parts fit my specific KTM 450 SMR?
