BMW Club of Northern California (BMW NorCal)

GUIDELINES FOR ASPHALT TRIALS

for the NorCal BMW 49er Rally

CONDITIONS FOR PARTICIPATION

START AND COURSE RUN

  1. The score will be taken from the best of two trials through the course. Based upon place or capacity, the organizers may omit the second run. An announcement about this will be made to the participants prior to the beginning of the contest.
  2. One can ride one's own vehicle or one that is loaned. But no one vehicle may participate more than three times in a contest.
  3. Two participations by a rider using a false name are not allowed.
  4. Obstacles will be placed in the course so there is no stretch through which a vehicle could sprint.
  5. The course must contain at least four (4) obstacle tasks, the last always being the finishing stop line.
  6. The sequence of obstacles is chosen by the organizers using those suggested in this document.

Pre-Ride Workshop

The organizers will guide a pre-ride through the course as time permits. Each rider will be coached by the organizers. This pre-ride will be organized: there is no riding without permission to be on the course.

SCORING

  1. Numbers of riding mistakes will be converted to a Error Points (EP) using the conversions in the Evaluation Table below.
  2. Scorings will be public - mistakes will be displayed on a board or by hand signals from judges. Mistake scoring will be determined by the scoring in the obstacles scoring section below.
  3. Times through the course are directly converted from seconds to Time Points (TP) E.g., a course time of 32.24 seconds = 32.24 Time Points.
  4. Error Points (EP) are added to the Time Points (TP). The resulting sum is the total of Penalty Points (PP) used for final scoring. PP = EP + TP
  5. The winner is the rider with the smallest total Penalty Points. In the case of a tie on total points, the one with the fewest error points wins. If both the time and error points are the same, then there will be a "runoff". If the result is still a tie, then the winner is decided by a coin-toss.
  6. Contest Interruption The following violations will stop the contest for a rider:
    • Failure to be completely stopped at start time.
    • Omission of one or more course tasks.
    • Failure to follow the instructions or sequence of the course.
    • Obvious help in improving the results by a third party.
    • Use of help devices.

OBSTACLES SCORING

The event organizers will use special scoring of the obstacles as indicated for each obstacle below. If the obstacle is sufficiently badly run, it may be construed as a contest interruption as described above. Special rules about foot touchings are as follows:
  1. The whole course counts for points - the feet may not touch the ground between the Start and Finish stop lines, including indicated intermediate stop lines. At the Finish stop lines, the rider must stop without touching and then ride off the course.
  2. Every touching of the ground will count as at least one mistake, up to a maximum of 10 mistakes on one course. More than 10 foot touchings will be a contest interruption.
  3. Extreme leaning causing the shoes (or bike parts) to touch the ground will not count as a mistake.

SLALOM

(Inline or offset count as distinct obstacles)
A minimum of 7 cones or unstable poles as markers
Scoring:
Knocking over a marker, or going outside the marked course - 1 Mistake
Incomplete running of the course (e.g., exiting through a gap) - 3 Mistakes

BOX


The rider must enter and exit by the selected gates, making at least two U turns.
Scoring:
Knocking over a marker, or going outside the marked course - 1 Mistake
Incomplete running of the course (e.g., not exiting through an exit gate) - 3 Mistakes

BOARD


The whole length of the board is to be traversed (twins spans for sidecars)
Scoring:
leaving the board - 2 Mistakes

TRAVERSAL OF TRACK

Cones and marked lines will determine the boarders of the track as explained by event organizers. Neither the front nor read wheels should touch the borders of the track.
Scoring:
Each touching of a border - 1 Mistake
Incomplete transversal - additional 2 Mistakes

SPIRAL

The rider is required to traverse a decreasing radius spiral with one entry gate and one exit gate. This is scored the same as a slalom.
Scoring:
Knocking over a marker, or going outside the marked course - 1 Mistake
Incomplete running of the course (e.g., exiting through a gap) - 3 Mistakes

STOP LINE

At designated stop lines, the rider must halt the motorcycle so that the front wheel is on the stop line (about 30 cm.) There will be at least one stop line at the Finish of the course. Another may be an intermediate obstacle.
Scoring:
Halting with the front wheel on either side of the stop line - 1 Mistake
Complete driving over the line (with the back wheel) - 2 Mistakes
The rider should stop without putting a foot down, and then ride off.


What part of the course is timed is determined by the organizers on the basis of safety. The organizers may also require an intermediate halt, with no touching of the foot to the ground, for the purpose of timing completion.


The course for the 2003 '49er Rally is pictured below:

This illustrates one legal path through the obstacles marked with red cones and lines, but this is not necessarily an optimal path.
