TK Dischi Freno SSP 5.5 Brake Disc Kit – BMW S1000RR K46 with HP Forged Wheel Hub (2009–2018)

Machined from premium-grade materials to the same exacting standards that inform MotoGP and WSBK campaigns, the TK Dischi Freno SSP 5.5 brake disc kit is engineered specifically for the BMW S1000RR K46 fitted with the HP forged wheel (HP4-pattern hub), delivering a measurable step up in braking precision for both road and track use.

Key Features

• Race-proven construction drawing directly on MotoGP and WSBK development programmes for validated real-world performance.
• Purpose-drilled ventilation pattern reduces disc operating temperature by up to 20 %, limiting fade during sustained hard braking.
• Reduced rotating mass compared to OEM discs improves chassis response and steering agility mid-corner.
• Homogeneous heat distribution across the friction ring maintains consistent pad contact and extends brake pad service life without compromising braking power.
• Lower lever effort required for equal deceleration, giving the rider finer modulation and greater confidence at the limit.
• Personalise the inner carrier ring in hard-anodised, black, red or blue to suit the aesthetics of your build.

Build Quality and Materials

TK Dischi Freno manufactures the SSP 5.5 to tight dimensional tolerances, with a 5.5 mm friction ring thickness and a 34 mm friction ring width that sit within the parameters demanded by Supersport-class regulations. The floating-mount design isolates thermal expansion stresses from the carrier, protecting both the disc and the caliper under extreme heat cycles. Each disc in this two-piece kit — one left, one right — is matched as a pair at the factory to ensure balanced braking front-to-front. The inner carrier ring is available in four anodised finishes, with the hard-anodised option offering the greatest surface hardness and corrosion resistance for high-mileage track day use.

Performance on Road and Track

The 320 mm diameter (with a 330 mm option also available) suits the stock S1000RR front end geometry while working with a wide range of aftermarket four-piston and monoblock calipers. The precision-drilled pattern clears pad debris and water efficiently, so initial bite remains sharp whether you are braking from motorway speeds or attacking the apex of a tight circuit chicane. Because the SSP 5.5 extends pad life, running costs over a full season remain competitive with lesser replacement discs.

Fitment and Compatibility

This kit is developed exclusively for the BMW S1000RR K46 equipped with the HP forged wheel featuring the HP4-pattern hub, covering model years 2009 to 2018. Before fitting, verify that your brake calipers accept a 5.5 mm disc thickness — this is the critical compatibility check for any caliper swap or aftermarket unit. Standard S1000RR caliper carriers may require a check against the 5.5 mm specification. Please also note that inner carrier rings finished in red or blue are subject to extended lead times; confirm availability at the time of order.
