Tire:
- Slick: Best grip in dry conditions, sucks balls in wet conditions.
- Intermediate: Good all-rounder, acceptable performance in both wet and dry conditions but it doesn't excel in either one.
- Rain: Best grip in wet conditions, sucks balls in dry conditions.
Mission (am guessing they mean transmission):
- Hi Geared: Higher top speed at the cost of acceleration.
- Normal: A balance between Low and Hi gearing.
- Low Geared: Great acceleration at the cost of top speed.
Suspension:
- Hard: Gives the bike a more nimble and responsive feel, provides less grip through a corner.
- Normal: A balance between Hard and Soft suspension.
- Soft: Provides for better grip around a corner but feels more sluggish, not as quick to respond.
Engine:
- Peekee (guessing they mean peaky): Faster/higher revving, provides for a higher top speed.
- Normal: A balance between Peekee and Wide.
- Wide: Slower revving and less top speed. Smoother delivery of power.
Brake:
- Hard: Quick, aggressive braking.
- Normal: A balance between Hard and Soft braking.
- Soft: Smoother more gradual braking.
Preferred setup will be dependent on the track in question and what feels right for you.
E.g. For a high speed track like Austria with long straights and gentle corners, a setup like this will provide the most benefit:
Tyre: Slick
Mission: Hi geared
Suspension: Hard
Engine: Peekee
Brake: Soft
