Information: This is my second ZXR, the first one was a H1 of 1989 that has passed 100kkm and that my young brother currently own (see my other bikes...). I purchased this 1990 H2 in Spain, without engine.
Originally, this was a French 100HP version, but the engine is now a Spanish "full power" unit.
I scratched the bike a few days after it was finished, wearing the original red/black/silver cowling and destroyed the left side one. Photos are showing the bike during a trip to Bretagne, when it was equipped with the stock headers fitted with a hand-built two-in-one silencer made by a friend of me. Notice that the sub-frame was not installed, bolting the cylinder head dirrectly to the chassis. Itīs possible using two threated spacers similar to the ones of the rear engine mountings. Different pictures of this bike competing in the early 90īs show the sub-frame was installed, but for street-use I didnīt noticed any difference about rigidity.
Later, I installed the green 2 parts cowling and racing rear seat of the later 1991 version. It fits quite well without too much work.
The bike now features KN filter + dynojet kit, +5š home-made ignition plate and silicone "hotwires". The escape is now a 4/2/1 "F1" manifold ended by a "Yoshimura" RS3, downsized to 45mm inside diameter for suitable low-end torque (the 2in1 silencer was too flow-restrictive, while it was the inversary with the original 55 inside diameter of the "Yosh").
The front brake discs are original but full floating ("Galfer" provided the rivets), and the "Brembo" PR19 radial pump operates through stainless steel brake lines.
A pair of lents provide the light in front, and the small mirors include turn signals, although they are not working. A pair of teflon pads have been installed since the picture was done (as well as Dzeus fasteners).
Since the bike is wearing Metzeler Rennsport tyres (I buy them from a friend who is competing the BMW Boxer-cup), it has changed a lot, being very, very sharper on the angle, moving quicker in any situation, and keeping perfect grip once the tyres are hot (it is horrible in cold, but going better with 2.6 bars in the front tyre for street use)
I was used to use it for week end with friends through the fabulous mountain roads of Catalonia, but my little familly decided me to change it fot a more reasonable ZRX 1200 S (I mean that with this one it is possible to ride slowly...). Now I use the bike only on race-track with my brother, so I am thinking about next modifications to suit this new purpose.
