RadioControlled motorbikes 1:4 scale. Weight 3,2 KG. Dimensions L x W x H 52x18x30 without doll

FRAME 4 plates used to create the frame: 2 upper and 2 lower produced from 2 mm aluminum with laser cut technology, followed by black anodic, assembled together using 6 mm steel bolts and aluminum spacers created from solid blocks with CNC technology. This structure is designed to create a lighter upper part, which means a lower center of gravity, to obtain an awesome stability and perfect steering ability on any sort of surface. The upper part of the frame is ideal to locate the electronics, receiver and servos, as it is far and protected from water, mud, sand and debris. The lower part of the frame is the motor/ battery area. Aluminum spacers are used to resist to the torsional stress produced during extreme riding.

FRONT FORKS Upside- down spring fork, bolted to  the frame through 2 CNC clamps and 2 plastic connecting rods reinforced and  mounted on 8 ball bearing to create a really smooth and accurate steering effect. At the front end too all the components are produced from solid aluminum blocks with CNC technology, tolerances are kept to the minimum to obtain maximum smoothness operation during the compression/extension of the fork, fast steering responds and a tough package.

REAR FORK The rear swing arm is divided in 3 parts: 2 arms produced using die casting technology and a central part produced using injection molding technology in tecnopolimer. The rear fork comes pre-assembled, with the chain guide and the shock absorber holder.

BRAKE Working on the clutch bell to minimize the effort necessary to decelerate.

BODY in lexan trasparent.
