    sportcity suspension upgrades?

    Hey, just curious if anyone has done any kind of suspension upgrades/tuning on a sportcity... or maybe some kind of mod to the forks. In looking around I can't find any aftermarket shocks. Maybe it's not broke in yet, with only 400 miles, but I think the suspension could use some help....definitely doesn't feel as smooth as a big bike. Is there anyway to adjust the valving, either comp or rebound that you know of?

    Well you could always rebuild it with a slightly lower weight oil, see if that helps any. Though at 400 miles you are probably only starting to get broken in.

    For parts I would try to figure out who they had make the fork and try to buy generic and not Aprilia bits. I've got to replace my oil seals and wipers and the ones I am getting will probably cost 1/3rd of the price from Aprilia.

    Bitubo makes a set of rear shocks for about $600.
    Malossi makes a set also for about $400

    An email to Bitubo, might bring you some luck there. Most European scooter parts places have the Malossi shocks.

    You have 2 problems with a scoot. One is limited suspension movement. THe other is the very high unsprung weight at the rear. Throw in the effect of the small wheels and you've no chance of matching the compliance of a motorcycle.

    Try to make either the spring rate or compression daming lighter and you'll have it bottoming. Try to make it firmer and you'll rattle your teeth. Aftermarkt shocks help by fine tuning a little, but not a lot. I wouldn't use a lighter oil at the front. A heavier weight might help a little, but it's the rear suspension that's the real stopper when it comes to a decent level of improvement.

    VE.UK has the Malossi shocks for $300. Dunno about shipping, but probably around $60 or such.

    What makes you say it has small wheels? At 15" the Sportcity is a large-wheeled scooter.

    Have you tried adjusting the pre-load on the rear shocks?

    i turned the rear out as far as it goes (less preload). it was only 1 notch from all the way out to begin with.

    williamr, i agree i'm pretty limited given the travel. i was just wondering if there was something to be done to make it feel better. most of my experience as far as suspension comes from mountin biking. and i can tell you....there's a huge difference between a $200 OEM fork and a $1000 tuned fork with the same travel. having said that, i really don't want to spend 1k tuning my forks. just thought if there was some way to adjust the valving on the stock forks i woudl try that.

    and yeah....15" is larger than most scooters...but most motercycles are running 16 & 17s.

    Yes, Where are those Chinese "knock offs" of Bitubos when we need them? You know they are out there. It's just a matter of finding them and getting the correct number. Ha!

    Chinese knock-offs would be exactly what Chinese knock-offs always are, Complete utter fucking shit. Bitubos are fucking awesome! Have no idea on the malossi's though. havent heard anybody ever talk about em, and I dont know anyone that has em. I do have experiance with chinese knock-off shocks though for differant scooters, and they are just god awful and barely safe.

    And $300-400 isnt that bad, considering that ohlins and such will cost ya about $1000.
