Casings: The casings are very similar to the P200 and PX200 casings except that the flywheel bearing outer dimension is larger.

Cranks: The cranks fitted to the early Rally motors with Femsatronic ignition are hard to find. They can be replaced with a P200 crank along with a different flywheel side bearing from a T5. The Femsatronic flywheel will no longer fit the new crank so a conversion to either the later Ducati type 6V Rally ignition & flywheel or the typical 12V CDI ignition & flywheel off a P series is also required. Use an NU205 flywheel bearing and P200 crank instead of the original.

Standard Barrel: The standard barrel has two main ports and a smaller third port. The barrel is not really useful for tuning as all the ports and transfers are internal to the barrel casting.

Kits: The Rally 200 can take all the same kits as a P series bike

Ignition: The Femsatronic ignition system on the early Rally bikes was scrapped after five years and replaced with a Ducati system. The Femsatronic is easily identifiable because of the bright orange ignition module. The system can be changed to a Rally 6V Ducati system or 12V P series system but the crank has to be changed (see cranks above).
