How many miles have you got on your LX 150?
I have 40,000 and still runs perfect. (2008)

'09 S150 with 18,000 miles. Lately, about half the miles it racks up are at 60-65MPH GPS (yes, it'll do 65 at sea level in stock condition with a flyscreen and a properly-configured tailbag for streamlining. Barely.). (Your top speed may vary.)

Needs a bit of throttle to start. (I've gotten used to this. Maybe the vacuum petcock is having issues? Not a major concern since it idles just fine.)
Has the usual clutch howl. Probably ought to get in there and blow the dust out of the clutch bell one of these days.
Replacing the exhaust this week (odd sounds, apparently not anything dangerous -- might be catalyst coming loose or a rusted internal baffle).

On the whole, not bad for 9 1/2 years of occasionally very hard use.

Wish the orange paint was a bit less fragile, but I suppose that's the price of vanity.

Sadly they can outlive their owners.

I have a smidge over 20K on the leader 150 in my Piaggio Fly.

It's a very good motor when serviced as recommended.

And there are a few go fast goodies available for it that don't compromise reliability.

I think the only reason they never released a stock 190 version was that the GT series started as a 200 and they were worried about cannibalizing sales of the larger bikes (as well as the difficulty of managing expectations of the aircooled engine).

I think the frame and brakes would be up to it.

The LEADER engine series included a liquid-cooled 200 if memory serves, so it should have been possible with the correct gearing (without re-gearing, it'd be easy to wind the engine up to RPM that would drastically reduce engine life).

49,600 miles on good old Leo before Judy decided the view was better from above.

Hope Leo is in good hands and doing Judy proud.

Piaggio did make an air cooled 200 Leader. And it performs about as well as the 150 air cooled engine. The big reason they didn't make a 200cc LX is that the market for it would be so small that it wouldn't make economic sense to do so. But putting a 125cc engine in the GTS does.

When I had the 190 kit installed, I also has the Polini up gear kit done at the same time. It made quite a difference. The main restriction on the Leader 150 is breathing...2v head really restricted the potential.

About the only thing I didn't do was hot cam originally offered by Vespa Soho. This increased valve lift and duration. You can get the same grind from a place called Web Cams online i think.

Does anyone know if the Air Cooled 200cc leader offered in Europe had a 4v head like the liquid cooled 200 GT? I thought I would ask before going Unicorn hunting.

I seem to recall that the other issue with the LEADER engine in the LX series is that the intake length is too short -- and can't be made longer without sacrificing the underseat storage.

Info from this thread (particularly posts by Oopsclunkthud and the chart posted by MODNROD).
