|Under 5′||50cc to 125cc||–|
|5′ to 5’6″||50cc to 125cc||–|
|5’6” to 6’2”||150cc to 250cc||70cc to 110cc|
|Over 6’2”||250cc and above||125cc|
5. Suspension Setup
The suspension system absorbs impacts, provides stability, and enhances the rider’s control and comfort while riding off-road.
Install the front forks and rear shock absorber, adjusting them according to your riding preferences and terrain requirements.
Additional tips for stiffening your dirt bike suspension:
