    Many scooters, one great engine.

    Many different brands of scooters share the water or air cooled minarelli motor found in the SR50, Scarabeo 50, Rally and Mojito. These include the Malaguti Scooters and Yamaha scooters. If we share what we know about the aprilia with other brand owners perhaps we can learn more about these fun bikes.

    Ok I'll begin with listing (long) Minarelli HORIZONTAL engined scooters.

    Some are AC (Air Cooled only) but it's just a couple of parts different from the LC version and both can be transformed to the other version without much hassle. All AC/LC cilinders fit AC/LC cases. The engine cases are exactly the same, only some difference if it has a rear disc or drumbrake. That's all.

    Aprilia:
    SR50 AC/LC
    Rally AC/LC
    Habana
    Area 51

    Benelli
    491
    K2

    Italjet
    Dragster

    Yamaha/MBK
    Aerox/Nitro
    Neo's/Ovetta

    Malaguti
    Phantom
    FireFox

    info needed

    DRT do you know if anyone converted the Zuma engine to watercooled, and if so what cylinder did they use. i have a MHR level 4 on my bike and as far as i know that is the best kit around. if i am wrong let me know.
    in hawaii we ride the fastest street mopeds ( scooters ) in the world.

    Hmm Zuma..isn't that the USA Booster? In that case it has the Minarelli Vertical engine, not horizontal. There's probably people that turned it to liquid cooling, but I guess that's all home-made.
    Maybe there's some LC kit somewhere...

    hey guys, I have a problem. I ned to know what is the acceleration time with a competition 50cc or 70 cc scooter. I said they can go from 0-100 with 5 secs but some guys say thats impossible and I want to show them that their wrong. so please, say here or give me some links where I can read about highly tuned competition scooters.

    they are wrong at the end of the day lets not get carried away
    the most tuned Mhr kitted scooters in europe achieve
    0-100Km/h is about 8.5 -9 secs
    they are putting out on average 22 hp

    8.5-9 sec for a 22 hp scooter?? I think it's a very very bad result, my old EVO AC bike did much more better accelration and it wasn't 22 HP (maximum 15 I think). Iit was untuned+21 mm carb+Shot.
    I think a 22 HP bike can do a very hard accelrartion. With my old AC EVO I used the Shot, because with the Giannelli Shot it was fery fast from 0-60 km/h (1.5-2 sec) but after that it was lazy, but it could do approx. 6.8-7 sec (with standard secondary gears and Malossi primary gears). But the accelration depends from the final gear too 5-5.8 sec isn't impossible!

    And here is a bike with only bolt on parts, nothing special:
