BST GP TEK Carbon Rear Wheel Yamaha YZF-R1/M RN32, RN49 & RN65 (2015–2026)

Forged from MotoGP heritage, the BST GP TEK carbon rear wheel for the Yamaha YZF-R1/M (RN32, RN49 & RN65, 2015–2026) is a statement in both engineering and aesthetics. Weighing just 2.4 kg without bearings and spacers, it pairs pre-preg carbon fibre construction with a CNC-machined 6082 T6 aluminium hub and Titanium Grade 5 hardware — a combination that defines what a purpose-built track wheel looks like and how it performs.

Key Features

• Ultralight construction at just 5.29 lbs / 2.4 kg (without bearings and spacers), reducing rotational mass for sharper acceleration and more responsive handling.
• Pre-preg carbon fibre rim paired with a CNC-machined 6082 T6 aluminium hub for an optimal balance of rigidity and weight savings.
• Titanium Grade 5 inserts, bolts and nuts throughout — exceptional strength with minimal mass penalty.
• Carbon fibre inner spacer reinforces structural integrity without adding unnecessary weight.
• DOT E and JWL certified, confirming the wheel meets rigorous standards for track use.
• BST Ultra-High-Speed 90° aluminium valve with cap included as standard.
• Backed by a 2-year manufacturer's warranty for complete peace of mind.

Design, Finish and Heritage

BST has spent decades supplying carbon fibre wheels to professional racing programmes, and the GP TEK range distils that pedigree into a wheel accessible to serious track day riders and club racers. The finish options — from the deep reflective quality of High Gloss to the understated sophistication of Satin-Matt, the raw structural beauty of Forged-Carbon, and a range of solid colour anodised finishes — allow riders to tailor the wheel's appearance to their machine without ever compromising the engineering underneath.

Each rim is hand-laid using pre-preg carbon fibre, a process that ensures consistent resin distribution and fibre orientation for predictable, repeatable structural behaviour. The result is a wheel that looks as purposeful as it performs, whether fixed to a Yamaha YZF-R1 in full race livery or a meticulously prepared track-spec R1M.

Track Performance

Reducing unsprung and rotational mass is one of the most effective ways to improve a motorcycle's dynamics, and the GP TEK rear wheel delivers measurable gains in all three areas that matter most on circuit: acceleration out of slow corners, stability under braking, and agility through directional changes. The carbon fibre inner spacer contributes further structural stiffness, ensuring the rim maintains its geometry under the extreme lateral and torsional loads generated in competition conditions. Radial load rating stands at 283 kg, static load at 551 lbs / 250 kg, lateral load at 720 Nm and torsional load at 1,043 Nm.

Please note: GP TEK wheels are designed exclusively for competition and track use.
