1Fuel – Petrol/oil mixture
The motorcycle is fitted with a two-stroke internal
combustion engine. This type of engine requires a
mixture of petrol and oil.
To ensure the correct working of the engine, the following are
recommended:
- Use high quality petrol, with an octane rating equal to or
above 90 (RON + MON)/2 or 98 (RON).
- Use 2T synthetic oil.
Warning:
- If the recommended oil is not available, use semi-synthetic oil.
- Do not mix different oil-types.
Mixture ratio: oil, 1.5% of petrol volume (50 parts petrol to every
0.75 part oil).
Note: we recommend first preparing the mixture in a suitable
container and then filling the fuel tank.
Fuel tank
This has a rapid access cap Aand a vent hose Bto allow gases
produced in the tank to escape.
- To open the cap, lift the clip in the direction shown by the arrow
and turn to the left.
Warning! Regularly check the cap seal and vent hose to ensure
they are leak proof. Risk of spillage.
