Tweaking rules to keep the 690 out is a moot point as they aren't dominating the class, so far not even a podium finish. There are always going to be bikes with a big advantage over others in a class like this. A BMW 1200GSA in the same class as a KTM 950 SE? That's crazy and certainly not a fair fight but seems to me the whole point of this class is racing with the wrong equipment and doing it with a big smile on your race. Being that it's a struggle to find enough guys wanting to race, why not open up the rules or make exceptions. Keep the 652cc min but wave it for certain bikes like the KLR650, 650 V-Strom, DR650 (others?).
