What is the difference between AMA Superbike and MotoGP?

Discussion in 'Motorcycle Talk' started by BentValve, Apr 26, 2006.

  1. Ive only recently began watching these races on TV, how does MotoGP and the AMA Superbike differ?

    Can someone list out all of the different sport bike racing organizations and classes?

  2. +1

    funny, Im the same... not quite following it 100%. I almost posted this same queastion last night haha

    Is it the diffrence of the twins and I-4's?

    and are the GP bikes 2 strokes?

  3. The ama stuff is based off production models.
    Moto gp is factory only bad boys, non production race only models the regular joe can't buy.
  4. Moto GP...Prototype bikes not based on commercially available parts. Weigh around 330lbs- put out about 250 rwhp.

    AMA supers Based on production liter bikes. Allowed to modify motor and suspension. weigh around 350lbs- put out about 210 rwhp.
  5. I am not sure on all the differences but a few I know... AMA superbikes are souped up regular bikes made to be race ready, lightend, more powerful, but stock design engines, and all that jazz. MotoGP bikes are striktly race bikes with (depending on the exact bike) usually inline 4s, V4s and v5s(3 going forward 2 going back)

    I'm no expert but the basic layman difference:
    -AMA bikes are based off of street bikes. There are different classes which limit what mods you can do to the bikes. Obviously the top Superbikes allow the most modifications but the bottom line is they are based on street bikes.
    -MotoGP on the other hand are one off custom built machines not limited by homologation (meaning they don't have to base them on street technology). And they are 4 strokes limited to 990cc's but will be limited to 800cc's as of next year.
    MotoGP is very analogous to Formula 1 in relation to cars. e.g. skies the limit technology.
    Ok, someone that know more than me can fill in all the details (or just copy and paste the respective rule books!) :mrgreen:
  7. Yeah. What they all said.

    MotoGP - like Formula 1, these are testbeds. non-production race bikes. 3 classes: 125cc, 250cc, and 500cc/990cc 4-stroke. current bikes in the 500/990 class are all 990cc 4-stroke machines and is the blue ribbon main event... the winner of this class is considered the best rider in the world.

    World Superbike - 999cc production based 4-stroke motorcycles. these are highly modified versions of production bikes you can buy on the dealership floor. WSBK is the international platform.

    AMA Superbike - American Motorcycle Association's "feeder class". it has become world reknown as a premier superbike league. a lot of guys go this route to get to WSBK or MotoGP, though many end up coming back to this class. GENERALLY the same rules for equipment as WSBK.

    but i do have one question... wtf is "Formula Extreme" besides a platform Honda created just so they could dominate something?

    GP bikes are traditionally 2-strokes, but due to a rule change back in 2002-2003 or so, they bumped up the displacement for 4-stroke bikes from 500cc to 990cc, but set them in the same class. it was to help offset the power issue with equivalent displacements between 2-stroke and 4-stroke platforms.

    so now they have 125cc, 250cc, and 500/990cc classes in MotoGP.

    as for the motor configuration, if i remember correctly, all current MotoGP bikes feature V configuration motors. many reasons why, i.e. ability to extract more power, width, centralization of mass, etc.

    The 2 stroke 500s are not even allowed anymore, the Formula extreme class is the full on souped up 600 class, slicks and many engine mods. Seems there are way to many ama classes.
  11. They need to let the 500cc 2 strokes run with the smaller displacement 4 strokes of next year. That would produce some good racing!

    ama = skilled riders.
    wsbk = super skilled riders.
    motogp = psycho riders.
  13. :thumblef: its exactly what it is.
    plus the fact that ever part there using u will not be able to find it in any shop.
  14. BULLSHIT!! I could go to shucks right now and buy Valentino Rossis GP bike!

  17. wsbk..ive not heard of that one...are any of those races broadcast on cable?

    So Mladin would get his ass handed to him in MotoGP?

    Nicky said last year Mladin would have no problem competing with any of those guys, "no one will compete with Rossi" Mladin did race in gp one season with a really bad Cagiva, his time is long past, as far as getting a gp ride. As far as wsbk having better riders, thats one of the biggest misconceptions out there. I would put the top 5 ama guys against the top 5 Wsbk anytime. The WSBK really is not old at all and does not have the tradition the ama has. In fact at testing this spring at philiip island mladin was faster than the whole lot of them.

    AMA Classes:
    Superbike - Extensively modded 1000cc production bikes ~ 200+ HP
    Superstock - Lightly modded 1000cc production bikes, bolt-ons only basically
    Supersport - Same as Superstock, but with 600cc production bikes
    Formula Xtreme - Extensively modded 600cc production bikes

    World Superbike Classes:
    World Superbike: Pretty much same as AMA SB
    World Supersport: 600cc version

    GP Classes:
    MotoGP - Prototypes only, no production parts allowed ~ 990cc 3,4,5 cylinders mostly, but changing to 800cc next year ~ 250+ HP, sub 340 lbs. Best of the best ride here.
    250cc GP - 2-stroke GP bikes, NSR250, RS250 et al.
    125CC GP - 2-stroke GP bikes.

    I'm sure I've left out one or two, but that's the basics.

    Generally speaking, yet the best riders are found in MGP, with WSB and AMA following. Now, whether or not Mladin would do well in MGP is a subject of great debate. IMO, he's a great rider, period. Give him a good bike and some time to learn it, and I'd be he'd do really well. Hayden basically did just that - went from dominating AMA to being a "good" rider in MGP. He eventually worked his way to being one of the "top" riders in MGP, but not dominant by any means.

    Is WSB better than AMA? I don't think so. I'd rate them as being pretty equal overall. There are fantastic riders in all of the classes.
  20. Thanks Jrod, thats probably the only useful post ive ever read from you here or at any of the other forums ive run into you at.:mrgreen:
