  • Page 12 TERRAIN 125 (MY21 EURO5) Running in Your New SINNIS Motorcycle After purchasing a new motorcycle there is a ‘running in’ period for the engine. It is vitally important that the motorcycle is successfully managed through this running in period as it will have a direct impact on the service life motorcycle.
  • Page 13 TERRAIN 125 (MY21 EURO5) Brakes Observe the following guidelines: Avoid excessively hard braking and downshifting. Sudden braking can reduce the motorcycle’s stability. Where possible, reduce speed before turning; otherwise, you risk sliding out. Exercise caution on low traction surfaces. Tyres can slip more easily, and braking distances are greatly increased.
  • Page 14 TERRAIN 125 (MY21 EURO5) Engine Braking Engine braking helps slow your motorcycle down when you release the throttle. For further slowing action, downshift to a lower gear. Use engine braking with intermittent use of the brakes to reduce speed when descending long steep slopes.
  • Page 15 TERRAIN 125 (MY21 EURO5) Riding in Wet Weather Conditions In wet or foggy weather, there will be low visibility and poor adhesion between the tyres and the road. Check tires for wear and check there is sufficient tread for optimum grip. When riding into low visibility or on slippery roads, keep to a safe speed and do not accelerate, brake or turn suddenly.
  • Page 16 TERRAIN 125 (MY21 EURO5) Parking Try to park on a firm level surface. If you must park on a slight incline or loose surface, park so that your SINNIS motorcycle cannot move or fall over. Make sure that high-temperature part cannot come into contact with flammable materials.
