Ray Superbike Prototype


   Hey there. I have been busy recently building my own bike. Yeah, custom bike. I already order Lifan 250cc engine(a racing spec engine), and using delta box frame. I got that from Skyline. For the fairing, I try to design it by copycat some from Ducati and Aprilia design. In few months, we will see how this works. But for now, only the frame and the engine are ready, but the fairing still on design work. It could take some time, but let's hope it's work!

Ahhhh, this will be nice.

       There are 2 types of 250cc Lifan engine. V-Twin and parallel Twin. I pick the parallel twin, since it produces nice sound and great top speed power. Lifan is made in Taiwan but there is authorized dealer in Malaysia. So it's easier for me to get the engine. I list down the spec of this Lifan engine that I gonna use for my bike:

Type: Double-cylinder,four-stroke air-cooled hand-clutched 250cc
Displacement:233ml
Compression ratio: 9.2:1
Primary reduction: 3.631
Bore x Stroke:53mm x 53mm
Max.Power & Rotating Speed:13kw/8500r/min
Max.Net Power & Rotating Speed:12.5kw/8500r/min
Rated Power & Rotating Speed:11kw/8500r/min
Max.Torpue & Rotating Speed:15.5N.m/7000r/min
Min.Fuel Consumption: ≤354g/kw.h
Ldling Speed:1400r/min
Ignition:CDI
Starter:electric starter
Lubrication: Pressure/splash
Transmission: 5 speed

        As stated, this engine is using air cooled system. So I have to use oil cooler radiator, to make sure this engine has long lifespan. This is a racing spec engine, so it is not suitable for daily use. It's okey, I will get another bike. This gonna be my collection anyway. Besides, proud to have my own custom bike.
