If it was an open class

Now that they are to the point of purposely de-tuning the bigger four strokes on occasion, I think you guys are on to something with the weight regulation of an open class. Would be cool to see what some engineering and a squillion dollars could come up with

Definitely. I think we would see way more innovation on the factory bikes by removing the minimum weight rule than by removing the maximum displacement rule.

A few privaters ran near 400cc CR500s in the last few years of the 500 series. Being a short stroke engine, they worked very well with a de-bore.

I'm a bit tongue tied with the blokes name right now - a Surname starting with B, and quite a Pommie one ( and that, he is), who ran various Belgian MX series , and may still do so, for some time after retiring. I remember reading an interview with him and him saying it was the best engine he ever ran.

One of our Brit contributors here should have a better memory of his name. Was he Chris Burnham?

I'd love to see an Open Class. Just naturally aspirated engines as a limit. I think around the 400cc size for 2ts could be the sweet spot for them, and, I'd welcome a return of genuine grunt, with big capacity 4ts, made 'minimally'. A smaller version of the JBS Racing M1, is what I'm thinking of. Modern weight saving techniques could bring 600+CC 4ts back with a few small manufacturers, and perhaps a big manufacturer. I've read / heard several times from riders of the 600/ 650cc 4ts that the engines would be more than competitive with modern bikes, it's their weight, old geometry and suspension that would just need to be sorted. I'd love to hear and see a variety of engines out there, instead of just the cookie cutter, blarping scream of high revving 450 4ts.

Won't happen though, we can't even get 300 2ts in the 4 stroke handicapping class. It's just a piss poor situation.

Shayne King was the last rider to win the series on a 2 stroke, and it was a 360, right on the lower limit,
