Can't work out why they don't just make mx2 250 two strokes and mx1 450 four strokes... Would make so much sence
No, that sort of BS is not what we need.
Just:
125cc Class
250cc Class
Open Class
No concessions to Any type of engine. Open class - basically so I'm not seen to be favouring anything. The 500 class, Always had various sized engines used in it. In the GPs, even when "500"s had become the norm., there were a lot of bikes with smaller capacities . Maxiumum power, that can be used on the dirt, is not a problem with say, 350+cc engines, of Any type. It's the power delivery / engine weight / size and feel, that becomes to variable / preferential thing for riders And Factories.
A Simple, 3 Class System, like we had before things turned to hell, is All that is needed.
The MX2 / 250 class being more costly to compete in?
It's always been the case - in "real life" and even "Factory Team" scenarios. Unless, of course, when it was HRC putting so much into the 500cc MX GPs, with their RC500s. And Yamaha with the 87 / 88 OWs.
500 2ts, for the average rider, and even highly skilled, competitive at high level riders ( look at the last years ( well, most years) of the 500cc MX class in the US (and even GPs, with the 2ts still around), '500s' were 'relatively' cheap to run. I remember a Dirt Bike magazine comparo between Bartolinis Husaberg 500 (whatever size it was - he was the holeshot King in 500 GPs - well, he and his brother were) and Lamsons CR500. Lamson being a non factory rider, at the time. The CR500 was said to still be on it's std piston, even after most of a season, of Nationals and numerous other races. In the US, you had blokes like Gene Naumec (sp?) in the top 5.
Same thing for the 450 class, basically. It's mostly moving power 'around', to suite the rider. It's easy to get more HP out of a 450, but, you don't Need much more. It's about usability, and rider prefference.
But, without a doubt, 250 4ts, REALLY make things expensive, when you are 'keeping up with the Jones'', be it at club , or National level. Just like it was with 125s - but Far More damaging to your wallet.
It's why that young Kiwis' (Bastards
" title="Angry" class="smiley">
- Enslave NZ Now! [you've Got to see that video], I say) family, and a few others, raced a 250 2t, to win the OZ 'D' / 19yr old ?? class, this year. I'm amazed that DK is allowed by Yamaha, to race the YZ 250. Perhaps, they are outselling the YZF, over the ditch?
