"From the first time I tested Pro Vac, it was impressive.
I was straight away one second a lap faster and the bike seemed even easier to ride.
I've been using pro vac ever since. "

"At the start of the season I did quite a bit of testing with the Ballards team,and whenever we tried Pro Vac I was quicker and had my fastest times.
Its been on my bike since then."

"I really liked the Pro Vac on my WR250F. It gave it a lot more power off the bottom, made it easier to start and reduced the engine braking. "
