HiPer's PROFill advantages are weight, superior cornering performance, ease of installation, affordability, and the ability to make quick adjustments for maximum suspension performance and traction.

Weighing more than a half pound per wheel less than other flat prevention systems and unable to absorb water, PROFill gives riders increased performance. PROFill can be inflated through the normal valve stem and requires no special tools to tune tire pressures.

PROFill eliminates the cornering chatter and vibration of other systems reducing rider fatigue while increasing cornering performance. To add more performance, PROFill is available in soft and hard compounds which can be mixed together for medium compounds tuned for the specific track and conditions.
