alpha racing swing arm pivot (modified bearing point)
-4 mm (in front), +1 mm (higher) for more mechanical edge grip (while accelerating in inclined position), more traction
At the same time suspension is getting more sensitive and less progressiv.
To realise the modification without engine demounting a dressed to size 46 mm socket is needed. Please ask us as needed.
Fits for:
- BMW S 1000 RR 2009 - 2011
