alpha Racing WSBK Camshaft Set Stage 4.1.1 BMW S1000RR (2010-2014, HP4). Camshaft set alpha Racing stage 4.1.1, BMW S1000RR 2009-2011, 2012-2014 and HP4, IN 11,5 mm, 256° / EX 9,6 mm, 252°, vibrofinished.

The new alpha Racing camshaft kit "Stage 4.1.1" is the further development of the already very successful "Stage 4.1" kit. As a result of extensive tests and dyno runs, the total-open valve time (256° at 1mm Lift) and valve lift remain unaffected, but by optimizing the intake camshaft’s ramp-profile, even more power could be generated over the entire speed range. These modifications allow better adjustment possibilities of the valve timing and as a positive side effect, by reducing the valve acceleration, and reducing the valve train vibration.

For fitting these cams it is required to use special valve springs (Part Number: 1134A100D00-01). Includes (1) alpha Racing intake camshaft, (1) alpha Racing exhaust camshaft, and (8) alpha racing low profile spring pockets 0.8mm. Please note that BMW S1000 RR (2015-) engines will use the alpha Racing WSBK Camshaft Set Stage 4.2 available in this SHOP.
