The race proven Supermotoland B-Kit is the simplest and yet most effective engine tune. The kit consists of the DVR stereo exhaust system and a Vortex ECU with maps tuned to give the best power options whilst maintaining drive-ability and good throttle response.
This is a plug and play kit for the 2019 to 2025 Husqvarna FS450 and KTM SMR450 supermoto bikes.
The engine does not need to be opened. All that is required is fitment of the DVR exhaust system and then the plugging in of the Vortex ECU (replacing the oem ECU).
Performance gains are impressive with a 5 hp gain over a very wide rev band from the stock bike when compared to the B-kit.
The B-kit must be run on 98 (European 98 ron) gasoline or better. The kit is very reliable and easy to fit and maintain.
Check out the graph in the product gallery to see the power improvement on the Supermotoland dyno. On our dyno a stock bike produces 54 HP and the B-kit takes it up to 59 HP (10% power increase).
Improvements are also made to the quick shifter, engine braking and initial throttle smoothness and response. On the 2023 to 2025 models the shifter will now also work between 1st and 2nd gear changes.
The vortex ECU will come with a selection of 10 different fuel and ignition maps, including a map for the race start and for the noise test. these can all be selected and used by easily turning the x10 dial on the ecu. Fuel levels can also be trimmed for fine tuning (instructions will be provided) by using the 3 fuel trim dials on the ecu for low, mid and hi throttle position fuel trimming.
