Piaggio/Aprilia/Vespa 200cc question please?

[MODNROD]

OK.
I want a scoot to get to work. For me that involves 100km one-way, stay for 4 days, ride 100km home. The road is all highway stuff, a bit bumpy, rolling hills (little bubby ones, this is Australia!). Just to make it interesting, one of the trips is at night with the roos and sheep, and I have 10km of gravel. I still want a scoot, so there!
The sensible thing to do would be to buy a maxiscoot (if you read this Farquar, no I still haven't got one yet........dammit!), but the thing is I like the smaller scoots. I reckon I've had more fun trying to hang onto a Vespa 250 at 100kph through sweeping really tight bumpy highway bends in amongst mates on sportsbikes than anything else I've ridden, hooooge fun.
Anyway, a friend at work has offered me his 2009 Aprilia Sportcity One, nearly new at a good price, and I'm inches away from pulling the pin and getting the thing. It's a 125 air-cooled Leader motor, but a 200cc kit is genuine Piaggio bolt on piston/cylinder, and a Polini upgear will let it sit on 100kph for hours on end. I'd get a Vespa GTS, but they run to $5000 2nd-hand with 30K on them. This Sportcity with a 200cc kit and an upgear will come out under $2500, and has 800km on the clock. Only thing I'm not sure about is highway manners, and real-world economy. It only has 6L before reserve, so I would need to get 30km/L (70.5 mpg US) otherwise I need a jerrycan extra, no fuel stops on the way. I know they handle well, but at 100kph are they really nervous and skittish?
Secretly I hope so, to make the weekly trip more interesting......

So, all you Vespa LX150 owners, Beverly 200 owners, Sportcity 200 owners (all the older carb models), do you get this sort of economy at these speeds from this Leader motor? If you only get 25km/L or so (under 60mpg US), I might have to keep looking, I'm trying to avoid carrying extra fuel.

If I was sensible I'd get a X-Evo 400 or Burgie 400, but I'm not.
I drive my twin-turbo Supra on the gravel.
I dragrace a Vmax, even though I know it will break.......again.
I have been known to stay out at night past 9:00pm.
I have been pulled over for dragracing my daughters 50cc Hyosung scoot in the city (well. me and 4 other 50cc riders ).
I'm also old enough to not care!

Let the flaming and experience begin.......

MODN, I got no hard experience for you but wish to thank you for some interesting, if speculative, cogitation time. Found myself wondering as a gloomy and worried actuary might: If I hit a kangaroo at 100kph at night on a rural road, would I rather be on 12-inch wheels or fifteens? Luck wif it, Mate.

[MODNROD]

Happy to be of service man!
Hitting a roo isn't necessarily a given at any time. I think even if you worried at it, stressed on it, and practically willed it into action by constant thought, it still isn't a fait accompli......
I reckon if I rode by and run over the toes of a boomer on either 12" or 15" wheels he would be pissed equally.

Another thing on this particular Sportcity choice........it's air-cooled and carby. That is a HUGE plus for me.
Being an electronics tech, stone-age simple is highly valued, I much prefer stone-age to space-age.

I've got a ET4 with the 150 Leader engine and a Malossi 190 top end. I also have the taller Polini gears, and a Malossi variator. If I accept the stock odometer as accurate, I am getting under 50 mpg, so yes, you would need to carry gas.

[MODNROD]

Bugger.
Still, thanks for your feedback mate, it sorta confirms what I'd heard. I might have to get creative with heads and intake/exhaust to get the efficiency up if I picked it then.
Not that is necessarily a bad thing.........

It's hard to find an air-cooled scoot around 200-250cc and 15-20HP nowadays isn't it?

[bman]

Something like this might work for you.
Never mind, liquid cooled.

[MODNROD]

Im starting to think liquid-cooled may be the only option, if I'm strict with my 25km/L at least @ 100kph up light hills. If I lived in the city the decision would be intantaneous.

I could probably make the 200cc AC Leader that efficient, or even a different brand (Yamaha/Kymco etc) but not without a fair bit of application to heads/cam/carb etc, which while fun, is a bit of a pain. I haven't had much luck with liquid-cooling on bikes out here in the past, I guess the 50*C temps we sometimes have may not be helping!

Interestingly, an air-cooled motor can run perfectly well in these temps (like my VW Bug), as long as you have a short quick shot of water through a reticulation nozzle aimed at the forced-air cooling entry point every few minutes (I use a cylinder head temp guage and a push-button for a washer bottle motor), while water-cooled seems to reach thermal overload eventually, even with big radiators and extra fans.

Mostly I just like the air-cooled simplicity, but I guess liquid-cooling may have to do the job.

Hell, any scoot is better than a tin-top.

[redhandmoto]

Do it. I'll hold your coat.

Plenty of photos, then, please.

And wow! A periodic spritz of cold water into the cooling air intake: that, you gotta love.

[MODNROD]

Hey man, good to see you again!
I have to admit, the perverse side of me would enjoy sucking the mirrors off a really nice Vespa 250 with a little aircooled scoot!

Hope you didn't have too much damage? I only saw what was on our local news, but it had top billing so must have been a bit harsh.
Hope everyone over there got through OK.

EDIT: Oh yeah, I forgot. I don't actually have to do it, because someone else has had the same idea, and is 1/2way through it here......

Holy Mackeral. That guy is using science, has charts and page-wide graphs with numbers to three decimal positions and stuff...when I first got into little bikes, I understood there would be no math...

Please carry on - ain't nobody else doing it in west Oz

And all ok here - storm-wise, we dodged the bullet.

Probably a few I guess, but no-one I know. Although, a really good mate of mine who works for the in-laws family farm here (actually, he's more like a brother really!) has about 10 old Vespas back home in Germany, ranging in horsepower from a mild 20HP, up to 35HP with liquid cooling.........all on small frame 50s and 60s Vespas that weigh in under 100kg.

We delivered farm stuff to the city 300km away last week, so sat there next to each other discussing/plotting/scheming hotrod scooters for the 3 hours it took to get us there in the truck. He's going home to Germany for a month's holiday soon. Germay is THE home for all things scoot racing. They make lots of stuff. Really cool stuff. Only thing is I don't know how big his suitcase is!

The thread in MV is more about outright power, whereas I'm more along the lines of just enough extra torque at reduced revs to maintain economy at slightly higher speeds, but it is indeed what started me thinking that maybe this little Sportcity could be made to work OK.

Good to hear everythings sweet over there.

[Tuonized]

I have the old 2005 Sportcity 200cc with 120000 kilometers on the clocks. I have done most of them on highways (or equivalent). The consumption is about 4-4.3 liters per 100km. So it is close to 25km/l you mentioned above.

I would not advise you to get smaller scooters or scooters with smaller wheels to be riding on the highway. Sportcity is very steady and has good brakes.

For my job I do 44 km round trip. I have done it at times with Gillera runner 125cc, Vespa gts 300cc, Piagio liberty 150cc and of course my own Sportcity. Sporcity was the best of them all.

[MODNROD]

Thanks mate, that's very good experience!
Much appreciated.

[Kubla]

I would suggest a Honda helix, but I do not know if they sold them in Australia
250cc liquid cooled, indestructible, holds a little over 2.2 gallons (8 liters) and I get 60 mpg with my tall windshield and my 400 pound fat but on it
