Steve,
The ride day was for the KTM and Berg demo bikes only. The only personal bikes were from the invited Pro's (Grabaham, lees, Wonka, Dukes, and Horwood), and a few helpers. I covered the event for EMD so had my bike there testing out the Roc Stompa Steering "dampener".
The test rides went for 30mins each. So if you tested three bikes that gave a pretty good ride anyway. If you were real keen the "Clarence" and Newnes riding areas surrounds the MX track, so you could make a full day, weekend, or week of it if you wished.
Be sure to get in early for next year. Now its started, I'd say it could prove pretty popular.
