Hi
I'm new to vespa and two strokes. I have an px 200 1986. In theory I'm a speed freak (in practice just want be startled once in awhile when giving full throttle). Why are smallframes the sportiest bikes? When you look around the craziest builds is like 180cc falc by some Italian dudes. Is there any reason why you prefer smallframes instead of largeframes?
Best regards from a clueless dude from Sweden

It has been said that it is more fun to go fast on a slow bike, than slow on a fast bike.

Or something like that.

I can understand that... but coming from bigger 4strokes like tuned 1250cc sportster the difference between smallframe/largeframes doesn't seem that big.... thought that it had to have some other reasons

Perhaps the smaller, slower, cheaper scoots are more fun to mod than the more complex bikes or the light weight improves the resulting power-to-weight ratio.

For me smallframes are “sportier” in that theyre physically lighter, have a smaller wheelbase and that the motors rev out more then their large frame counterparts. Higher revs creating more horsepower on a lighter weight bike is pretty fun

As someone with both a smallie and a largeframe, they ride very differently. Very. It might seem like it should be a small difference on paper, but the P200 feels like a big thumper in comparison. There are other things worth considering - unlike the largeframes, the engine weight is better/more centrally distributed in smallies so the handling is a bit more even in both directions. They're just very "flickable" little hellcats

I understand. But is there any reason that you can't get similar power out a px200? Been watching a lot of dyno pulls with smallframes up to 180cc and there is many 30-40hp bikes out there.
This video is just crazy

Ok. Seems that the best is to tune my px200 to a 20-25 hp and then get a smallframe to go more bazerk

A smallframe engine has a better overall design that can cope with higher horsepower than a largeframe engine. A smallframe also has much more engine ground clearance (when leaning WAY over around corners on a racetrack) than a largeframe. The current aftermarket smallframe cylinder kits offer a better power to weight ratio than the largeframes. All that being said, i would much rather cruise down the highway on my heavier PX200 than on my smallframe.

I think is has to do with the feel. I let my 19 year old son ride my kitted VBB. He took a ride, I asked him what he thought and he shrugged. After that I let him ride my mostly stock (slightly ported and better jetting) 1964 V90, which is much slower. He came back and couldn't quit smiling. I have to agree with him, while it's not as fast it's just a lot of fun to ride.

Smallies are lighter and better balanced. The weight is more evenly distributed.

The smallframe clutch isn't hanging off the crank like a bitch.

Smallframe is agile, & light (power to weight ratio)
10" may feel agile, but a PX is a pig in comparison...
ohh, then there is 8"!
