So, it's good to hear that later 19th unit fits 1st gen bikes, but what about vice-versa ? I have 2013 bike but I also have an almost new ABS unit for 1st gen, will it work on 2013 bike ?

A 2013 model is a 1st generation bike. Is the nearly new unit you have for a 1st or second gen bike? Reading your question it appears to be for a 1st gen in which case it should fit just fine. Have you compared part numbers between year models?

Yeah, that's exactly what I did. Turns out that Yamaha used to install ABS p/n 23P-85930-09-00 from 2010 to 2012, and from 2013 until the end of manufacturing the new p/n 23P-85930-19-00 was installed. So, technically only 2010-2012 years were the 1st gen years, and 2013 was some kind of transitional. First I was hoping that only 1st gen ABS was prone to early malfunctioning, but then I've found several mentions that the new p/n isn't significally better. The thing is - two years ago I bought a new ABS unit for 1st gen (that I used to own that time), and, while my newly bought 2013 bike ABS is still formally functional, I just thought that installing a brand new unit may be a better idea...

I found this info on Yamaha part numbers on the cms (parts vendor) site. According to this, the parts should be interchangeable.

About Yamaha part numbers

Part Number in the format XXX-XXXXX-XX-XX


XXX-XXXXX-XX-XX
The first three digits are the Model Code (every model in the Yamaha Product Line has a unique model number) all parts are given a Model Code of the first model they were used on.


XXX-XXXXX-XX-XX
The middle five digits are the Basic Code number and indicates the actual part, i.e. 11631 = piston; 11311 = cylinder, etc.


"W" substituted in the first position of this five-digit group (000-W0000-00-00) indicates a factory assembled kit which differs in content from the original assembly used in production (i.e. 2M0-W0046-00-00 – Rear Break Pad @$$’y).


XXX-XXXXX-XX-XX
The next two digits are the Design Code and Design Change digits (so 01 means the part has had one design change). This part may or may not appear different, but it will be interchangeable with the original part.


XXX-XXXXX-XX-XX
The last two digits are the Color or Finish Code.

Well, in theory.

Follow my logic: Partzilla states that ECU p/n 23P-8591A-70-00, being the most modern older ECU revision (-70- is for design changes inside the gen, newer gen start with 2BS-) is compatible with 2012 and 2013 year model bikes. In the same time 2012 was the last year the older ABS unit (-09-) was put on bikes, since 2013 they started to put the the -19- p/n. Since ECU is interchangeable between revisions, ABS unit also should be (imagine you put newer ECU on older bike with older ABS, - formally for the chain ABS-ECU this is the same as putting older ABS on newer bike), and direction "more recent/more older" doesn't matter.

yes that unit you have will fit your 2013 bike, theres a thread on here somewhere where a guy is running a abs unit off a 2017 on his 2011

Yeah, I've seen it, but I'm about to do the opposite - older unit on a newer bike. However, seems like this will also work, since all the ABS units are compatible with the same set of ECU.
