Yamaha SR 250 Tracker

1981 Yamaha Sr 250 Street Tracker. Modified Frame, Honda CB 50 gastank, hand sewn seat unit with a build in pocket for a phone plus phonecharger , no battery, minimal wirings within the frame tubes, kickstarter added, 18” Excel wheels.


The donor bike had approximate 25000 km on its odometer with only one ownership. So the engine just needed a small tune up.

The frame got detabed, rear loop welded, and a mounting bracket for the ignition key added.
Finished in a flat black powder coating.

To adjust the geometry of the bike, the original hubs got powder coated and laced to 2,5 x 18“ black glossy excel rims fitted to dunlop k180.

After tying out serval rear shocks, we decides to go with the stock ones, and also lower the front fork 4 cm by the springs and 4 cm by the tripple clamps. to get a more agile steering angle and the right side line.


the battery got replaced by an condensator and a kickstarter unit from the xt 250 was fitted. the wirings were adjusted to the new position of the components and alls visible wires were hidden and placed in to the frame tubes to become as clean as possible.

To get an flat track look we decided to fabricate a two ton seatunit, which imitates the seat cowl of the flat tracker seat pan.
The seat got a hidden pocket to store a mobile phone, which can be connected to a built in charger.

A Cb 50 tank was fitted to the bike to underline the horizontal lines and to structure the side view. the graphic on the tanks are kept simple and they follows the frame lines and connects both sides of the tank to each other.
The minimal use of blue color sets some highlights to the bike.

by removing the airbox and relocating the electronic components under the seat and tank, we totally tided up the rear triangle.

to get a right stand of the bike a crowbar was fitted as a side stand to handle the new height.

All light components were chosen to be as simple and clean as possible, like the motogadget handlebar blinker and the small 41/2“ Frontlight. the rear/breaking light is fitted under the rear fender.
