Who's better, a straight fork or an inverted fork?

A wide range of locomotive suspensions

Although the motorcycle has only two wheels, there are many suspension systems, such as the most classic Periscope suspension, Honda's Pro-Link rear suspension, Kawasaki's free-balancing front fork, Ducati's skyhook suspension, Harley's soft-tail shock damper, Yamaha's rocker suspension, and so on

We often say that the positive fork and the inverted fork, generally belong to the periscope suspension, the use of coil spring, piston rod, inner cylinder, outer cylinder of these core components, in the vehicle operation by up and down telescopic operation to absorb the ups and downs from the road, and then achieve a stable body shock absorption effect.

Forked and forked

In the interior of the shock absorber, the most active component is definitely the helical spring, which is not only flexible, rapid response, but also strong fatigue resistance, the traditional front suspension (fork), the position of the helical spring is on, and many times can only withstand the constant force

Later, engineers have rich imagination, if the shock absorber is upside down, the movement of the spring is closer to the irregular vibration, so that the spring can better resist the reaction force from the road, so there is an inverted shock absorber, referred to as the reverse fork

Advantages and disadvantages of the inverted fork

Inverted shock absorbers have two core advantages, the first is to reduce the unsprung mass, that is, the mass below the spring in the suspension system. Objects with more mass have more inertia and are less responsive to external forces

Therefore, in the inverted front fork, the inner tube is designed to the bottom of the overall front fork, the diameter is smaller, the mass is lighter, the mass below the spring is lighter, the feedback on the road is more sensitive, and the tire can better maintain the ground state

In addition, under the same conditions, the overall rigidity of the reverse fork will be better, the positive fork is used as the main force point, and the reverse fork is used as the force point with a larger diameter sleeve, and the strong external sleeve is connected to the frame, so that the transverse force of the entire shock absorber is better and the anti-distortion ability is stronger
