Modern Vespa

I have never ridden a P/PX 200, but I know they're 2 stroke. I've ridden enough 2 stroke bikes, quads, snowmobiles etc. to have a healthy respect for the POWER 2 strokes can make, so I'm wondering, will a P200 outrun a 4 stroke GTS?

My copperless pennys:

The P on the take off.
But the GTS on top speed and maintaining top speed.


I rode my GTS to San Diego and back with one of the Royal Bastards. We were crusing at about 75 mph, I wouldnt try that on a P200.

Gotcha. I'm curiuos as to how fast a P200 can be MADE to go then..I gotta figure somebody has hopped one up and made it scream like only a 2 stroke can.

You jack monkey, you didnt say that.

Tricked out P might beat the GTS in the short run, but I dont think it would in the long run. I think the P would get hot and seize, now if someone had a water cooled kit for a P, maybe, but Ive only seen a one water cooled kit for a P and that was years ago. Someone on here might have seen something recently.

Depending on the distance, but I prob bet on the GTS.

I'm thinking of the Yamaha Banshee I rode some time ago..I got on it, wondered why it had a speedometer on it that went up to 140mph..I found out why! I guess not all 2 strokes are the same, even though, the old 250R 3 wheelers are air cooled, and holy shit do they run!

I can't see a P beating a GTS over any distance. Off the mark the GTS flies aided by not having to change gears.

Bone stock: The GTS.

But, if you took the P200, did some engine porting, put in a Malossi 210 piston and ran it in properly, used a banded clutch so it wouldn't explode from the torque, added a T5 carb properly jetted or maybe a Vortex carb, and added a JL righty exhaust pipe? Yeah, it could probably outrun the stock GTS for a while. But eventually it's going to get hot unless you have it jetted for WOT riding. And you're going to have to stop for gas almost twice as often because all those mods aren't exactly great for your gas milage. And, finally, your reliability on a vintage torque monster is never going to be as good as a stock GTS.

As a sort-of but not-quite comparison, my '03 Stella had a 177 kit with a bunch of mods like that and it was a lot faster than a GT200. But it wasn't faster than the GTS with direct injection instead of an old fashioned carburetor. And my MPG was only in the mid 50s to low 60s.

I would've bet on a manual being faster off the line than an auto because you could launch at higher revs with the aide of the clutch.

How long do you want the hand hovering over the clutch on the 210 they can pull more bhp than a GTS and are lighter so they are quick alright!
But they will be on the (seize) edge if you want to hold a 75 cruise.


I expect this will be disputed, but any distance and the GTS will run down a 210!!! Sheesh that will get them going.

Sorry your answer 210 18-20 bhp, a GTS standard 16.5 Rear wheel figures.

both fun scooters but the gts, and really all piaggio automatics are just plain all around better scooters out of the box, and they aught to be, even the most recent PXs are thirty year old technology

since piagio started making scooters, they have been improving them with every model and year... the P series is the best manual shift scooter ever. they are as far as that technology can go...

so came the 'leader' motor. and they just keep improving that...

the GTS is a better scooter than the P series. it will go faster for longer.

a kitted P with a good rider might beat a GTS on a race course or drag strip... but thats not really a fair comparison...

...with this said, remember i'm a "vintage" guy. i'm stating all this without prejudice.

what color is each scooter?

My stock GT keeps up just fine with kitted P-200's regularly on the mean streets of Cowtown. However my hand goes WOT right off the bat and I just wait for my bike to catch up to what I'm giving her. The P's are gearing up and therefore more in control of their rate of acceleration.

Top end I think the P's have got me beat. Not sure. I average 120km/hr (75mph) and can do that for hours. We had two P-200's ride 8hr.s to Trail BC this past weekend averaging the same speed I would have done; 75mph. So air cooled P's can do the distance given the right motivation. That being beer and bacon and lots of it.

The P200 can be made to make more power than the GTS so it will be quicker. It's not uncommon for a tuned P200 to create 25hp or more at the rear wheel. But both the P200 and the GTS have limits on top speed due to gearing.

While you could get the P200 up to higher top speeds than the GTS you can't hold it there for long without risk of twisting the crank or exploding the clutch. I think you could build a T5 or a smallframe that could match the GTS on top speed and best it everywhere else but you'd still be looking at a life span of ~5000 miles.

Now a lambretta, on the other hand, has no excuse for not being quicker and faster than anything else ;)

I had my kitted PX200 doing 130kph, and it could hold that speed WOT for ages without seizing. But my hand was poised over the clutch just in case.

The kitting consisted of ported Malosi 210, Sito-plus exhaust, PHBH30 carb, PM's upjet kit. Could have gone a fair bit further with an upgear kit and reed inlet manifold.

Whenever I pushed the scoot hard, I had my hand over the clutch. Picked up the habit back in the 1960's with my GS150. They were notorious for seizing and breaking rings. Had to break the habit with my GT and GTS.

My 1986 stock PX200e is a little faster off the start than my well-maintained GT200. It's lighter. Top speed is considerably better on the Modern machine.

I have both and bone stock the GTS would always beat the P200.

It's not terribly hard to make a lambretta engine 30+ horsepower. The one with the highest HP on the dyno at vegas was 37hp, wasn't it?

GT200, easily. You can't beat the straight line speed of an automatic, or from a standing start. They're just faster and cleaner engines.
