Call us crazy, but the 600cc bikes to be used in 2011 for the FIM’s replacement of the 250cc Grand Prix series sound less exotic than the current crop of sportbikes we can buy at the store right now. After comparing the specifications, we’re thinking anybody with a 2009 model, track-day prepped, RSV-4, YZF-R1, 1198S, GSX-R1000, CBR1000RR, etc., will have a bike with cooler gizmos and capable of keeping pace. That just sucks.>

We’re beginning to see the light, but it’s painful florescent light. Even if the FIM had been smart, adhered to heritage and created a 500cc open 4-stroke class with no traction control and restricted use of exotic materials, we’d still have antiquated race machines. That’s because for $30,000 or less, new motorcycles have things like traction control, fly-by-wire throttles, on-the-fly variable engine mapping and nonconventional firing orders. Not to mention gobs of usable power. We don’t have to wait until 2011 to buy this kind of stuff, just the Spring. By 2011, we’re guessing traction control will no longer be exotic but standard.

By 2011, exotic motorcycles will be probably be electric. Yeah, we know, we know! They’re silent, moving parts aren’t causing tiny explosions at rapid rates, ears are for bleeding. But let’s face it. Combustible engines are just so 20th century. Well, it’s either that or underground non-regulated racing with d.i.y. run-whatya-brungs accompanied by Tina Turner singing We Don’t Need Another Hero.

We all need to accept the fact that we’ll soon be saying, “There used to be this thing called Grand Prix racing, and it was sooooo coooool.”

2. Inlet & Fuel System

2.1 Variable-length inlet tract systems
are not permitted.
2.2 Only one throttle control valve per cylinder is permitted. No other moving devices are permitted in the inlet tract before the engine intake valve.
2.3 Throttle bodies will have a maximum internal diameter (must be perfectly circle except for the area of dent or groove to allow the injector to come out) at engine side out-let of:
42 mm for 4-cylinder
48 mm for 3-cylinder
59 mm for 2-cylinder
2.4 Fuel injectors will be restricted to a defined type (tba, based on cost).
2.5 Fuel pressure must not exceed 5.0 bar.
2.6 No artificial cooling of intake air or fuel.
2.7 Only air or air/fuel mixture is permitted in the induction tract and combustion chamber.
2.8 No direct fuel injection into the cylinder/head/combustion chamber.
2.9 Fuel specification will be for standard unleaded fuel (commercially available EU-compliant “pump fuel”).

3. Exhaust system

3.1 Variable length exhaust systems are not permitted.
3.2 Noise limit will be a maximum of 120 dB/A, measured in a static test.

4. Transmission

4.1 A maximum of 6 gearbox speeds is permitted.
4.2 A maximum of 3 alternate gear ratios for each gearbox speed, and 2 alternate ratios for the primary drive gear is permitted. Teams will be required to declare the gearbox ratios for each gear used at the beginning of the season.
4.3 Electro-mechanical or electro-hydraulic clutch actuating systems are not permitted.

5. Ignition, Electronics & Data-Logging

5.1 Data logger system will be supplied by the series Organizer.
5.2 Only the ECU/fuel injection control units supplied by the series Organizer are allowed to be fitted to the motorcycle. Electronic control units include the timing transponder,

JPY75,000 (about Euro650).

6. Chassis

6.1 Chassis will be a prototype, the design and construction of which is free within the constraints of the FIM Grand Prix Technical Regulations. The frame, swing-arm, fuel tank, seat and cowling are forbidden to use from a non-prototype as series production road-going motorcycle.

7.4 The number of slick tires allocated to each rider per event will be controlled.

8. Materials & Construction

8.1 Construction materials will be limited to exclude expensive “non-conventional” materials and manufacturing methods (a list will be issued).
8.2 The following components must be made from iron-based alloys:
Valve springs, camshafts, crankshafts, connecting rods, piston pins, brake discs.
8.3 Engine crankcases and cylinder heads must be made from cast aluminum alloys.
8.4 Pistons must be made from an aluminum alloy.

9. General

9.1 Number of machines: the team can scrutineer
only one motorcycle per rider.
9.2 Number of engines: a maximum of 2 complete engines per rider is permitted at any event. Teams will be required to register engine serial numbers at Technical Control on the day before the first practice.
9.3 Apart from the above regulations, all other construction criteria, dimensions and specifications are as per the FIM Grand Prix Regulations.
9.4 The engine (excluding exhaust, throttle bodies and ECU) used in a race is available to be purchased by another competitor in the same race for a fixed price of €20,000 (Euro). Such purchase request must be made in writing to Race Direction within the protest period, that is within 60 minutes after the official end of the race. The transaction and delivery will be completed immediately at the end of the 60 m
inute protest period and will be underwritten by IRTA. Teams refusing to sell when presented with a valid request will be disqualified.

    Oh bloody hell, they’re doing a Formula 1…

    So the engine is mostly boring, but the frame must be something unique. That strikes me as odd.

    And that engine-buying rule sounds like a recipe for killing off low budget but succesful teams. Sunday afternoon end of race, buy their engine. Next thursday, new race event, so 3 days to get a new engine. Keep that up for a few races…

    Oh well, it’s been fun.

    I agree the engine buying rule sounds crazy. Probably everybody remembers the whole thing in which mc claren was fined big time for spying on Ferrari. Now at Fim you just pay to have a look in someboby elses kitchen. And only the factory backed teams can afford that

    What strikes me also is how the 4 cylinder engines are favored. Higher rpm and just slighty heavier than a 3 or 2 cylinder bike. Wouldn’t it have been great to have a revival of the 80′s tt2 class. 600cc twins. And why do the bike have to carry so much weight. Why not stick to the 100KG limit of the 250 class.

  • Doug

    They should have been 400cc max and allow
    tubo and supercharging. There also should be no limit on the no. of cyl.

  • David

    This rule is written very strangely. It should be proscriptive, not exclusive. For example, “No oval cylinders” does not rule out the probably superior but still complex to manufacture eliptical. Why not just say “Must be circular bore, +- some very small variance.”

    Also, a factory needs a reason to go racing. That reason is marketing to generate sales: win on Sunday, they will buy on Monday. This recipe seems to have none of that potential.
