    Default Referee Decisions - 2015

    This thread is here to post all referee decisions for the 2015 season. I will add to it as the season progresses. Rest assured, all decisions posted have been discussed with the WMRRA Board.

    If it isn't here, then it isn't an official referee decision, and the 2015 rulebook is correct!

    Decision #1 - Ultra-Lightweight Supersport Allowable Displacement for Four-Stroke Twin Cylinder Bikes.

    Section P.7.g.II of the 2015 WMRRA rulebook allows four-stroke twin cylinder bikes up to 300cc. The question has been asked if the new Yamaha YZF-R3 (321cc twin) will be allowed to race in this class.

    The YZF-R3 will be allowed to race in Ultra-Lightweight Supersport for 2015. The following were considerations in making this change:

    1. OMRRA currently allows up to 321 cc twins in their Ultra-Lightweight Supersport class. This change will make the classes more uniform between the two clubs, making it easier on racers.

    2. It gives the R3 two Supersport classes to run on Saturday, instead of only one (500 Supersport).

    3. Yamaha has indicated they are willing to provide contingency money for those racing the R3, and prefer this class to 500 Supersport.

    As such, the following changes apply to the 2015 Rulebook:

    P.7.g.II - Up to 321cc four-stroke twin-cylinder [revision]

    P.7.g.II.1) - Street legal pump gas only (87-93 octane) designed to be run in street legal vehicles [addition, due to displacement advantage]

    Decision #2 - Use of Aftermarket Brake Master Cylinders in Supersport Classes for GSXR Models

    Question (paraphrased): Given the known issues regarding '03-'12 Suzuki GSXR front master cylinders being problematic, can GSXR motorcycles use aftermarket master cylinders when participating in eligible Supersport classes.

    Affected Rule: 2015 WMRRA rulebook, Section P.5.m - The use of aftermarket brake master cylinders is not allowed.

    Ruling: Suzuki offers a recall update for affected GSXR front master cylinders, and the update has proven effective. A local Suzuki dealer has verified that the recall update is still available. Accordingly, the use of an aftermarket brake master cylinder on Suzuki GSXR models is not allowed in Supersport classes, in accordance with the 2015 WMRRA rulebook, Section P.5.m.

    Decision #3 - Legality of Bodywork with a Superbike Tail/Seat in the Supersport Classes.

    This was not a direct question, but is a clarification of a discrepancy in the 2015 rulebook that was discovered when investigating a different question.

    It was determined in the Fall 2014 rules committee meeting that superbike tails/seats should be allowed in the supersport classes because there is little difference between the OEM seat and a superbike seat on most relatively modern bikes. As such, item P.3.h (requiring a stock seat base for supersport bikes) was removed from the 2015 rulebook. However, Section P.5.o still erroneously refers to the requirements for an OEM seat base.

    As a clarification, superbike tails are legal in supersport classes.

    Decision #4 - Legality of the "Cup" Version of the KTM RC390 in Supersport Classes

    Question (paraphrased): Is the "Cup" version of the KTM RC390 that is available through dealers eligible for supersport races?

    Affected Rule: Various portions of Section P - Supersport Regulations

    Ruling: Yes, the "Cup" version of the RC390 is eligible for supersport class races, for the following reasons and subject to the following conditions:

    1) While not street legal as sold by a dealer, the cup version is basically just a stock street legal RC390 that has been race prepped by the manufacturer. There is no difference between a local shop, mechanic, or individual racer converting a stock RC390 into race trim (i.e., not street legal) vs. the manufacturer doing it. The base bike is still a street legal model. (Section P.1)

    2) The forks are slightly different between the RC390 Cup and the RC390 street version, in that the Cup version has compression adjustment on the bottom of the forks versus the street RC390 forks being non-adjustable. However, section P.5.e allows for new fork caps and internals, thus potentially making non-adjustable forks adjustable. Therefore, while the cup version does have different forks than the street version, the effect of those is the same as what is allowed in the rulebook - adjustable forks.

    3) The cup version of the RC390 appears to come with larger front brake discs than the street version. These must be replaced with the same size and material discs as the street version, per section P.5.m.

    4) All supersport regulations not mentioned here must be followed as usual.

    Decision #5 - Round 6 Scoring

    Issue: There has been confusion among WMRRA members regarding how Round 6 race results are to be scored. As everyone knows, the round was a joint event with OMRRA, where both OMRRA and WMRRA racers were on-track at the same time. The primary question has been do the OMRRA racers count towards the "starters beaten" points, as defined in Section M.1 of the WMRRA rulebook.

    Ruling: Round 6 will be scored according to Section M of the WMRRA rulebook, and in accordance with the WMRRA President's Round 6 announcement to the club on 11/22/14. Although OMRRA riders were on the track at the same time, only WMRRA racers will be considered when determining finishing positions and points earned. WMRRA racer finishing positions will not be affected by the presence of OMRRA racers, and WMRRA racers will not earn points for the OMRRA racers they beat.

    This scoring arrangement only applies to Round 6 of the 2015 season. Future joint rounds may be scored differently.
