GASGAS 700 auxiliary tank kit features and benefits

KTM 690 2019 tank

Extra 100 km/60 miles fuel range

You get an extra 5,5 litres of gas (1,5 gallons) for your adventure trips :-) It means great freedom with total fuel range over 330km (205+ miles)!!!

Keeps original handling

Great benefit of our auxiliary tank solution is keeping the same dimensions and weight of your GASGAS 700 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 TwinAir filters

The small airbox uses the OEM intake flange yet provides better air in-flow. In combination with the foam filter from TwinAir 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. The GP dust cover is supplied with each kit.
