KTM 690 auxiliary tank kit 2019-23 features and benefits

KTM 690 2019 tank

Extra 100 km/60 miles fuel range

You get an extra volume of 5,5 liters of fuel (1,5 gallons) for your adventure trips. It makes great freedom with total fuel range exceeding 330km (205+ miles)!!!

Keeps original handling

Great benefit of our auxiliary tank solution is keeping the same dimensions and weight of your KTM 690 enduro. Simply the auxiliary tank is “hidden” in the bike and it does not add any extra dimensions to the bike so the handling of the bike is exactly the same as the factory 690.


Improved MultiAir filters

The small airbox uses the OEM intake flange yet provides better air in-flow. In combination with the foam filter from MultiAir designed specifically for the RADE/GARAGE, it gives you extra power (about 3-5HP) and torque (about 5-8NM) in 3000-6500RPM.   Moreover it is easily accessible so replacement takes only few minutes. The filters are pre-oiled, but when they get dirty they are fully washable and reusable, making them environmentally friendly.
