My latest ride which I will keep until I get my full license next year. Another little 250cc inline 4 pot screamer, this one redlines at 19,000rpm.
There are A/B/C/D models for the ZXR250. A models are 1988-1991 and are 45HP motors. B models are a rare race spec version with different CDI, cams, carbs and a closer ratio box from 1st to 3rd gear. C models are 1993-2004, have 40HP and were made in both Japan and Malaysia. D model is just a C model with the B model race-spec bits. Due to Japanese law, you get funny things like "speed lights" that light up at 80KM/h (easy to fix, remove the bulb), 40HP/32KW restrictions from 1993 onwards, and some bikes have electronic/CDI limitation to 180KM/h.
Mine is a 1999 built in Malaysia as it has safety stickers in Malaysian and has made in Malaysia stamped all over its bits and pieces. I've also had it up to 200KM/h indicated on the speedo while at the track so I don't think its restricted, apart from being a 40HP motor.
Pictures of as it was when I got it. It needed a service including valve shim adjustment which I gone done at work, since I work for a motorcycle shop now
I also got the timing chain and notoriously crap tensioner done (used a GPX250 one)
The carbs needed work (which I did at home) as there was a flat spot between 6k-8k RPM. The carbs have vacuum lines/vacuum fuel tap and the seals between each carb body are known to go brittle and fail. I replaced them, but I had to fight overtightened JIS screws (aka Japanesive phillips, but its not a phillips. If the screw head has a dimple, it's JIS and you need special JIS screwdrivers or you'll make a mess of the heads) to get the carbs apart.
After that I got an aftermarket exhaust, the stock one makes an incredibly dull wheezing, aftermarket much better

The plastic tubes on the tank are for the voltage reg/rec, which lives under the fuel tank. Mine had deteriorated so I got new ones, along with a new reg/rec
New rear tyre put on & balanced at work... fun fact... its an 18" rear rim, which limits tyre choice... I can potentially use a ZXR400 rim or ZR250 Balius rim which are both 17"
And just recently, some orange rim tape and ninja stickers to match the decals on the tank
