1988-Kawasaki-KR-1

1988 sees a lot of 250cc 2-stroke performance bike on the market. One of the best bike are this one, Kawasaki KR-1. Fitted with liquid-cooled 2-stroke 250cc engine 180° firing parallel twin configuration, this engine are able to maxes out 55PS  of power at 11,000RPM and have been tested at the Bonneville Speedway to claim the World’s Fastest Production 250cc as tested by Performance Bikes Magazine. The speed recorded is 225km/h. That is fast for a bike with just 123kg of weight.

Kawasaki Integrated Powervalve System (KIPS) was incorporated in the engine design to widens the power delivery of the engine so that it feels smooth in almost every RPM range. KIPS are still used in the current bike in 2013 as used by the KRR-150ZX.

Is there any of this bike available in Malaysia? Or is it never touch the ground here?  (more…)

The engine fitted to this bike is a 2-cylinder 90-degree V-configuration in 2-stroke mode cycle. It is forward inclined at 20-degree for lower center of gravity. The crankshaft is 180-degree and made to be strong and compact. To reduce the friction from the piston to the wall of the cylinder block, SBC cylinder plating is applied to replace the conventional cast iron sleeves. SBC stands for Suzuki Boron Composite that plates the aluminium cylinder inner walls with a special alloy plating that consists of nickel and phosphor alloy carrying boron bromide. This reduces the friction and increases the durability of the piston rings.  (more…)

suzuki_satria_120_R

After looking for a bike model from Suzuki on Google, I found this interesting picture of the 2004 Suzuki Satria 120 R which is marketed in Indonesia. The bike bears a significant resemblance of the Yamaha 125Z.

The engine are able to push 15.5PS at 8,000RPM and 1.50kgmf at 7,000RPM. Transmission is checked with the 6-speed gearbox. The tyre is wide at 2.50-17 at the front and 2.75-17 at the rear.

Modified Yamaha RX-Z Motocross Style

Ady Sevens shared the link about this Yamaha RX-Z modified to motocross style as seen on Mudah.my. This kind of mod is very unusual since most RX-Z are modded lightly just to make it street legal but powerful and fast. This one in motocross style are equipped with monoshock rear suspension and the exposed front suspension that it makes it looks very different. We can only see the RX-Z design cues from the unmistaken look of the fuel tank. Good mod bro!

Thanks to Ady Sevens for sharing.
