With Moto2 being successful so far, it was just a matter of time.

Title: Re: RIP 2-strokes Post by: Drunken Monkey on June 02, 2010, 05:42:04 PM Quote The class will be composed of 250cc four-stroke single cylinder machines, MCN reports, replacing the 125cc two-strokes currently being used. SPROING. Although personally, I was hoping for a bit more displacement, but as long as the power is in the ballpark of 33 HP, I'm all for it. Title: Re: RIP 2-strokes Post by: fastwin on June 04, 2010, 01:38:04 PM I read that Roadracingworld.com article he was referring to. They had a lot of problems getting a 450cc four stroke to hold together for a USA sprint race distance. Can't remember if it was WERA or something else. I can only imagine the stress a 250cc four stroke engine would have in a World Championship Moto3 race distance. I really miss the 250GP bikes... :'(

Although personally, I was hoping for a bit more displacement, but as long as the power is in the ballpark of 33 HP, I'm all for it. My carb'd Ninja 250 (with a somewhat built motor, granted) put out 34 HP. You're looking at a lot more than that for these bikes. Imagine 50-60 hp in a MotoGP race frame with a 4 stroke powerband. SPROING!!! I really hope they don't run thumpers though. Despite the weight savings, they'll just come to pieces on the racetrack. Title: Re: RIP 2-strokes Post by: Speeddog on June 07, 2010, 05:24:43 PM 250 single 4-stroke, unlimited tech?
IMO, somewhere between 40-50 HP, IE a bit less than 25% of a WSBK literbike. But they'd be borderline grenades. Same as if they're built-up 250 MX motors. Title: Re: RIP 2-strokes Post by: Spidey on June 07, 2010, 05:41:47 PM Just brainstorming here, but mebbe they should make them ride with actual grenades underneath them? Set to go off if you don't make a minimum time. Or if you try to get off the bike and run away from it cuz you realize you're too slow.
That'd make the 125/Moto2 bump-n-grind look like tea-time. It'd be awesome. Title: Re: RIP 2-strokes Post by: fastwin on June 08, 2010, 04:12:37 AM Wonder if they will make them use spec 250 thumpers ala Moto2 motors? If so I wonder which company will land that contract. Whoever it is they will have a tough time cranking out enough power to make it interesting on the track and at the same time keeping them from grenading... speaking of grenades.
Title: Re: RIP 2-strokes Post by: zooom on June 09, 2010, 04:06:06 AM WELL...I think it might be possible to make a motor for this work...something with a double connecting rod for balance like the old Supermono....
