MOTOGP » MSMA wants 600cc to replace 250GP

thats the problem with 'em, when something goes more often then not it's a big/expensive part! Rebuilds are more frequent too, with a 4t you just top it up with oil and send it out again.

I'd like to see nimble 450-550cc twins instead of "just another" 600 class.

Exactly 2t.
I started racing 100cc karts & as a kid it seemed like for every hour we spent on the track we were spending 2 in the workshop. Once I got onto bikes it was slightly better but not much ... at a stage I was spending more time with my 125 MX motor than my GF.

Now I have a 125 rotary 4-stroke kart, a few 4-stroke offroad bikes & I spend most of my time actually riding / driving them rather than fixing them.

From my experience of two and four-stroke motocross machines, even if a two stroke seizes its only a few hundred pounds to rebuild. If a four stroke goes wrong (valves frequently seem to) you're talking thousands. Even a four stroke piston is much more expensive. Maybe it's different for road racing?

I would like, for the replacement of the 250cc two stroke class, 500cc four stroke twins, and for added interest the option of a 750cc single cylinder four stroke thumper.
For the 125cc two stroke, I would like twin cylinder four stroke machines at 250cc, with the option of a 450cc single four stroke thumper.
People may laugh about the thumpers, but in this day and age of fuel costs and shortages, it might be a good road to explore, also they would have an effective weight advantage....not to mention a few other advantages such as maintenance costs etc.
Also, it is about time the industry moved away from 2/4 stroke and looked at rotary and diesel, liquid gas and compressed natural gas

OK, maybe I'm just riding my bikes harder than you guys!! Joking!

Why the hell are they so concerned with changing things anyway!? I'm looking at a full competetive grid on the TV right now: and a series which consistantly produces fantastic riders who know how to race.

They should be looking to get a few more manufacurers in MotoGP before messing with the feeder series'.

Rant over. Enjoy the race.

Cheaper, jokes aside ... u could well be!

Ricky, I think the plan is just to have a single support class & keep the Red Bull Rookies as a sideshow. It would be nice to see a supermono, but the different capacities for different config engines is a recipe for finger pointing & 'questionable' rules ... just look at superbikes at the moment.

This is true Dice, and I do believe it is time for the questionable Spaniard Mr E to exit stage: the thought of mighty thumpers, and all that would ensure, is extremely appetizing to an old man like myself

kind regards,

ricky

I think the best idea is a full on prototype 400cc class. The 2 strokes have had their day and just think what a v4 400 at 20,000 rpm would sound like.

As for costs, 4 strokes are way more expensive to run than 2 strokes. Do you honestly think the teams in MOTOGP just top up with oil and turn up the following week???

Actually, 2 stroke 125s & 250s are still very commercially relevant. What do you think most youngers learn on?
Intrinsically, 2 strokes are true racing machine - they will always develop more power capacity for capacity than four strokes.
And I'm sick of the con-of-the-century environmentalist lobby.
Let's just offset the carbon - bury an environmentalist every month and there you go. Make sure they are at least 6 feet under so the carbon can't escape.
