    UK Race Spec Z900

    I thought i'd give a bit of a lowdown on my Z900 Race Bike that I use in No Limits Streetbike Cup in the UK as I know there will be a few questions
    The bike was built by MSS Performance in Colchester (located with Colchester Kawasaki)
    Brand new 2021 Zero Mile Z900 was the start point
    Engine:
      Standard internals as required by the regulations
      Akrapovic headers, custom link pipe and hanger, Spark Force Silencer
      520 chain conversion running 14 or 15 front and 42-44 rear
      Translogic Quickshifter
      MSS gearbox mod to improve selection
      GB Racing engine covers
      woolich race tools flashed to ECU
      Lots of dyno time

    Chassis
      K-Tech IDS 20 fork internals
      K-Tech Razor R Shock
      Ohlins steering damper
      Lightech Adjustable Rearsets
      ABS Delete
      EBC GPFAX Pads
      MSS Brake lines
      GB Racing frame slider
      MSS bodywork -  Nose Cone, Belly Pan, Seat Unit 
      Renthal Superbike low rise bars
      Radiator Guard
      Metzler or Pirelli Slicks (180/60 rear)
      MSS Lockstops
    Decals etc done by Sublime designs

    I am sure there are loads of bits Iíve missed but these are the headlines

    Itís genuine a 125 BHP (not PHP Ė Pub Horse Power) - may get a couple more with a MWM Filter
    On the same Dyno the stock bike was 109bhp

    Cost wise  all in Ė wellÖ.. with buying a new bike under Kawasakiís Race deal, youíll not really get any change from around £16k - this includes MSS building it so it arrives ready to race

    Hey buddy, saw your introduction post and been waiting for this post. Where you based? Bought my bike at Colchester Kawasaki, which is where MSS is based isnít it? Iím curious about the gearbox mod youíve mentioned, specifically what is it, how does it work and what difference did it make?

    Cheers :028:

    Hey
    I'm down in West Sussex
    Yes MSS are at Colchester Kawasaki - I've been friends with the Morgan family for years and bought all my race bikes from them.

    So i had a problem with the bike jumping out of 4th gear when accelerating hard ... this is something that is quite regular with kawasaki's that are used on the track -  its the design of the dogs in the gearbox.
    we had the engine out and split to trim up the tolerances and i think they undercut also.
    Its superb now, especially with the QS -  not really an issue the average road guy will have and an expensive job..... so dont touch unless you have to

    Thanks for that. Yes, sounds expensive, so not something Iíll be doing lol.

    Another question about the GB racing bullet sliders. Currently got a set of crash bars fitted to the bike as I used to use it for commuting year round. Itís now just a play thing, so looking at something a bit more low profile and these caught my attention. Seen how they mount etc, but wondering how much they stick out. Would they protect the plastics if the bike was sliding down the road? Already got the case case covers, so just a question of how much these would keep the bike off the ground. If you could post a picture from above the tank, that would be great.

    Nice!

    I've been following a few of you from this crew on Insta. Always wanted to take my bike to MSS but never seemed to make the trip.

    I've got a 2019 with full Akra exhaust. It's been dyno tuned but always felt like it could be a bit better. That's the main reason I wanted to take it to MSS as they've already dyno tuned several Z900s for race and road. Kawasaki UK have major ties to MSS for racing as well.

    Have you ridden the Z900 in stock form and if so how is it power wise after MSS did their magic compared to stock?

    Also, have you modified anything to do with throttle response?
