Power Upgrade to BSR-X5

BSR-X4 Power Unit Upgrade Package – Boost Performance to 33kW (44hp)

This upgrade package increases the power of your BSR-X4 power unit or kart from 27kW (36hp) to 33kW (44hp). With this upgrade, you’ll gain an additional 10% torque and a 10% increase in top speed. This upgrade is exclusively compatible with BSR-X4 power unit models. For those upgrading to the X5 model, we recommend using a kart chassis with front brakes to handle the increased power and top speed safely. With the Drag Race mode gear ratio in optimal conditions, this upgrade allows acceleration from 0 to 100 km/h (60 mph) in approximately 3.5 seconds.
