 PREMIUM RACE FEATURES
When hundredths of a second can make the difference between taking the Holeshot and getting stuck in the pack, the XTRig Holeshot Device helps you get the perfect start by preloading the front suspension, lowering the centre of gravity and reducing front wheel lift for quicker acceleration.
The bike is also equipped as standard with a Triumph Racing Hinson clutch cover, a front disc guard to deflect debris and impacts, and a gripper seat cover to reduce slipping and enhance rider control
These premium components elevate the overall performance and reliability of the TF 450-RC. |
LIGHTWEIGHT AND STRONG
The TF 450-RC features a unique aluminum chassis, designed to provide a perfect balance of performance, mass and flexibility. The frame’s spine and twin cradle design offer exceptional strength while minimizing weight, contributing to the bike’s overall agility and handling on the track. Hand TIG-welded craftsmanship ensures durability and precision in every detail. The chassis has been race-optimized for longitudinal, lateral, and torsional stiffness, ensuring the best performance under extreme conditions. This allows for exceptional handling and provides the rider with precise feedback and control during intense riding. The result is a chassis that delivers top-tier performance and reliability, tailored for competitive racing. |
 LIGHTWEIGHT POWER ADVANTAGE
The light and nimble aluminum chassis of the TF 450-RC plays a crucial role in achieving its class-leading power-to-weight ratio. By minimizing the overall weight of the bike, the chassis allows the powerful 450cc engine to deliver exceptional acceleration and performance.
