We’re finishing a boardtracker where we’ve used this blade jumper (30900ST).
The swingarm is painted in the old original green color of the bike. The leaf springs, swings and the forks are chromed.
The handlebar has inverted vintage handles (1203240) which are reversed handles with cable control. On the brake side the cable goes over to a hydraulic brake reservoir to control the front brake.
The whole is completed by a very old headlight!
