Tuned ZXRs

This section is dedicated to bikes that have been heavily tuned/modified. Here you will find examples of what can be done explained in detail by the owners themselves.
The idea behind this is so that people can see a real life example of what can be achieved and take a look at what it takes to achieve the "complete package".
Where the owners have already set up their own website I have simply provided a link to it.
If you have heavily modified your ZXR/ZX7R and you think that other people may benefit from your experience send me an e-mail with a description of your bike and what you have done to it (for complex projects a step by step guide would be great) and, if suitable, I shall put it up here.

• Brian's fantastic ZXR750R Racer  Brian's passion, knowledge and attention to detail has turned his ZXR750R-M into a lightweight and very potent racebike.
  Do you want to know how "extreme" these bikes can go? Here's your answer!!!

• Pekka's 130+ bhp ZXR750J/K  91/92 ZXR750s have a lovely chassis and great looks. The K model engine is very raw and exciting, but how would you like another 20+ bhp? Pekka from Finland tells us how.



• Skydork's (aka Jeff) ZX7/9R  Many ZX7R owners think about putting a ZX9R engine into the ZX7R chassis, but most are scared by the complexiy of the task and don't know where to start. Jeff kindly put together an extremely detailed guide (with step by step pictures) on how he did it! Read on.



• Sigvart's ZX7/950R  With his conversion Sigvart moves the game on. He put a bigbored ZX9R engine into his ZX7R and tuned it. The result was an impressive 145.5bhp at the rear wheel. But why stop there? So In Phase 2 he tuned it further still.
  Mental? ......Oh yes!!!!!!!!!! TAKE A LOOK AT THIS.



• Sigvart's ZXR950R Racer!!!  This is the new home of Siggi's Tuned 950 engine. The frame is a '91 ZXR750RK one (ZX7R in the US). It is a stunning piece of work. I want this bike!!!
