The JUBU SEVEN 490 performance kit increases the power of the SEVEN 340 from approx. 170 hp to a whopping +245 naturally aspirated hp. The performance kit was developed in-house by our technicians and precisely tuned and extensively tested on our dyno and on the road. Thanks to the balanced set-up, extensive testing and the high-quality components used, there are no restrictions in terms of the durability and usability of the vehicle despite the increased power.

Benefits / advantages

• Performance increase of approx. +75 naturally aspirated horsepower
• Significant improvement in torque and performance
• Enormous gain in liveliness and sportiness
• Reinforcement of the engine block with forged pistons, steel connecting rods and upgraded connecting rod bearings
• Improved appearance thanks to the JUBU 4-1 stainless steel manifold with HJS 200-cell sports catalytic converter with E-mark
• Improved sound - but not unpleasantly loud. Can be used in normal road traffic without any problems! (original silencer can be retained)
