BMW Tracker SE Concept Bike

No bike off the rack - BMW R107 TRACKER

As with all of our bikes, we put a lot of emphasis on usability and performance. On this Tracker we used a 19" wheel in the front, which in combination with the Dunlop tires is geometrically completely different from all our previous BMW conversions. This meant that the geometry had to be changed and the fork tuned much softer, due to the very hard casing of the Dunlop DT3.

The engine has 1070cc and is built with our SE Big Bore Torque Kit, which does not require longer connecting rods. In the cylinder head work our SE Performance valves in the sizes Ex 39mm / In 45mm, there is a 320° camshaft installed, our programmable SE Performance ignition system and for the mixture preparation provide TM 40 Mikuni carburetors. The customer did not want dual ignition, which is easily possible with our 1070. Instead, the kit can be easily installed without any further mechanical changes. We are limited only in the compression ratio, here we go up to 10.5:1, with dual ignition we reach values up to 13.5:1. The output is 84HP and 90Nm, the maximum speed is 7,300 rpm.

All body parts are handmade from aluminum. Such custom-made parts can only be realized as part of a complex complete conversion and cannot be offered by us individually.

To the TÜV: Generally all vehicles are TÜV approved by us and fulfill the German laws. The exception is, a customer would like to have expressly made changes, which do not correspond to the regulations. Then such a vehicle is built ready for registration and accepted. After the TÜV, with the reference of the inadmissibility, the appropriate changes are made. In the case of the tracker, the carburetors and open filters are not registered, the 150 rear tire is not approved, and the position of the turn signals/tail lights are not allowed. Everything else is approved and registered.

The entire bike was custom built as a one-off for our customer and is not for sale.
