Brembo SBK T-Drive 6.75 Racing Pista Bassa Brake Disc for BMW S1000RR K46 HP Forged Wheel (2009-2018) 08C86953

For BMW S1000RR K46 riders who demand reliable, race-derived stopping power in everyday use, the Brembo SBK T-Drive 6.75 Racing Pista Bassa brake disc (part number 08C86953) is a direct-fit upgrade engineered specifically for machines equipped with the HP forged wheel and HP4 carrier. Drawing on materials and technology proven in the Superbike World Championship and MotoGP, this is a disc you can run hard on a Sunday trackday and trust on the road the following morning.

Key Features

• T-Drive floating system transfers braking force evenly and efficiently, delivering consistent bite lap after lap and mile after mile without fade or judder.
• Inox racing-grade stainless steel rotor — the same material specification used in WorldSBK, World Supersport and MotoGP competition — combines outstanding durability with a long service life that justifies the investment for everyday riders.
• At 6.75 mm thickness across a 320 mm diameter rotor, the Pista Bassa profile keeps unsprung weight in check while providing the thermal mass needed for sustained hard braking.
• Optimised for use with Brembo Z04 brake pads and compatible with the standard S1000RR calipers as well as Brembo M4 monoblock calipers and equivalent high-performance units.
• Precise OEM-matching fitment for the K46 chassis with HP forged wheel — no adapters, no guesswork, straightforward installation.

T-Drive Technology on the Road and Track

The SBK T-Drive system uses a radial pin drive interface between the aluminium carrier and the steel rotor ring. This geometry allows the rotor to expand freely under heat while keeping it correctly located axially, which translates directly into a more progressive, controllable lever feel. On the S1000RR K46 — a motorcycle that can overwhelm a standard disc at sustained high pace — the T-Drive design removes the inconsistency that often appears as temperature climbs. The result is a braking system that rewards confidence: you can push later into a braking zone on track and rely on the same response through everyday traffic.

Material and Construction

The braking ring is manufactured from Inox, Brembo's proprietary high-strength stainless steel alloy developed through the brand's racing programmes. It resists corrosion and surface rust far better than conventional cast-iron discs, which matters particularly for riders who cover road miles in variable weather between track sessions. The Pista Bassa (low-profile) geometry reduces the overall disc height compared to a full racing unit, making it well-suited to road-legal setups without sacrificing any of the core stopping performance.

Fitment and Compatibility

This disc is developed and validated for the following fitment:

• BMW S1000RR (K46) — model years 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017 and 2018
• Requires the HP forged wheel with HP4 carrier interface — not compatible with the standard cast wheel carrier
• Front axle fitment

If your S1000RR K46 was delivered with, or has been retrofitted with, the HP forged wheel package, this disc mounts directly without modification. Always verify the carrier type before ordering.
