BMW S1000RR HP4 Wheel Sprockets

[Leafy90]

Hello,

Can anyone tell me the best place to purchase various sprockets for a BMW HP4 wheel with a 520 chain. Ideally after at 42 tooth sprocket and I am finding it a nightmare.



Regards,

Matt

Alpha racing?

Alpha definitely.
https://www.ukracesupport.com/products/bmw-s1000rr-hp4-2009-afam-steel-rlk-superlite-rear-sprockets there's a 43 here. Not sure why you'd want a 42 that's very unusual for an S1000RR.
I was using Talon-Eng but I'm not sure they do much for street/track bikes now.
