I've just moved to building an R1 race bike for next season after being on ZX10R's
The bike I've bought is an ex BSB Stock 1000 from CFM, and over the winter I'll paint it up in my colours and add a few bits and bobs
My current 2016 ZX10R

The R1 I've just picked up :

I've got a good list of things to do to the bike to make it mine, starting with selling off the fairings if anyone's interested, as they're way too nice to use on the track (they were painted by the guy that paints Shakey's bikes), and they're not in my colours etc anyway.
I've ordered a couple of sets of CRC fairings to get painted in my colours, I'll fit a Thumb brake and probably get a new race dash for it too (It already has kit ECU/Loom), and I've managed already to source a few sets of spare wheels etc.
MSS have always looked after my ZX10R's, and they're sorting me a Spark exhaust so I can get it through sound testing if I do any trackdays as it's way too loud at the moment - It has a full Ti CFM race exhaust that makes about 110db static.
I'd be interested to hear some feedback on the Spark exhausts on R1's if anyone has used one ?
The idea is to get it finished by Feb as I'm out in Cartagena for a few days, so it'll be a good time to get all the set up stuff done and see how it compares to my ZX10R - I was out there this week on the Kawasaki, so I have some data to compare between the two bikes (even though I got bloody food poisoning on the first night and spent most of the time sat on the shitter or had my head in the sink)
I put the camera on for a session if anyone's interested in the track : https://youtu.be/AQO8HMWX8Mk
Anyway, I have loads of time on my hands this winter, and a laptop in front of me, so I'm sure I'll be on here with a million questions
