We have several questions about the sprocket for HP4, from dealers ordering the regular 1000RR sprockets for their clients. I thought it would be worth mentioning this on the forum. Your non franchise dealer, might not know the correct fitment.

RST_727 is for HP4 ( Replacing OEM sprocket # 8532146 ) 2013-2019
RST_727 is a BMW option for S1000RR ( Replacing OEM sprocket # 8532146 ) 2015-2018

RST_7 is for standard wheels S1000RR 2013-2018
RST_1790 is for S1000RR 2019

If this helps anyone, thats cool.

Link is only for your reference to see different models and years. you can see "Drawing:" there with the correct number.

I think the confusion comes from forged or non forged wheels. The HP4 has forged but is a 2014 where as all the other 2014 RR didn't have that option. 2015 was when it first became available. Thanks for posting, I will sticky this thread.

Do I understand you correctly?
1000RR (NOT HP4) could have the forged wheels as an option? 2015 and later??

Yes. S1000RR had forged wheels as an option from 2015-2018. HP4 had forged from 2012-2014.

S1000RR had forged wheels as an option from 2015-2018

Thank you. We will make a note for Supersprox clients, to alert them about optional forged HP4 wheels application

I have updated my original post, to include the information that bennymx has kindly provided about the optional forged wheels.

Some general suppliers of parts for motorcycles were confused as to which sprockets fit what bike. Because everyone assumed the S1000RR is the same bike in all years they forgot about forged wheels. HP4 being forged from 2012, 2013 and 2014. S1000RR only have cast wheels from 2010, 2011, 2012, 2013, 2014. S1000RR has cast and forged for 2015, 2016, 2017, 2018 and 2019 (USA). S1000RR 2020 K67 has cast, forged and carbon but the sprocket carrier remains the same unlike the older forged wheels which ran a different carrier and hence a different stud pattern

I should also note that in the USA the 2020 model is the new S1000RR K67. USA considers the 2019 model the older model the same as a 2018.

In Europe the new S1000RR K67 is considered a 2019 and the 2018 is the older model.
