Yamaha RX-Z Standard Look with Racing Spec Modification

Yamaha RX-Z Racing Modification with Standard Look
(Standard Modified?)

This RX-Z belongs to my mechanics who are now busy restoring the Yamaha 125Z that I have bought earlier last month. This bike is not for everyday use and used only on track. If you see this bike anywhere, beware as this bike can go 180km/h at 4th gear. You can imagine the rest. I'm against racing illegally on the public road. Please be careful and race on track only. Remember your loved ones.

Modification data:
CDI Race Spec Racing Bee
Stock ignition coil 1st model
Sprocket 16-35T
2.25 17" front, 2.50 17" rear tyre
Stock gear, previously fitted with racing gearbox but not good for sprint
Racing Bee racing clutch with stock clutch spring
Yamaha RX-K 1.25 piston with Racing Bee conrod
Top speed: >200km/h, maybe 240km/h as the meter can't read after 180km/h.
Note: Race on track and NEVER on public road!

All the pictures here is high resolution, so, click to enlarge!
