Modern Vespa

Hello,
I am the new owner of a 2005 ET4.
It has stock Pirellis, the rear is almost bald, the bike has 1950 miles on it.

I have searched and searched this for forum and learned a lot so far...thanks!
I have seen a few posts regarding upgrading to a Zippy 130/70 x 10 rear tire and that it is great. I have seen one or 2 that stated the tire was rubbing on the inside rear fender.

Does it rub, on any shock setting?
If the handling is greater, more stable, does not really deter lowend and enhances high end, why doesnt everyone do this?

If anyone could give me more details who have made the switch or did not make it because of reasons I would appreciate hearing them.

By the way, I live in suburbia, I have rode to work a few times, about 10 miles one way and I have several lights, stops but also have stretches of road that I run 50mph more or less...no interstate..so I need both lowend and high end. I need to be able to run and gun with all the cars in the area.

I am leaning towards making the upgrade but not sure if it is a wise decision.

thanks for your help

I have Mich.... (can't spell)on my ET4, back and front
Back tire gets about 3000 miles.
I go 45 to 60mph most of the time.
Handeling is good, I like the tire.
I see your question mine are 120

We have an ET4 with about 600 miles on a 130/70-10 rear Zippy.
I 'think' I felt a difference at first, but you get used to it, probably more 'new tire' feel than anything.
Whatever, it looks great, like it should be, nice and fat
No rubbing issues, we run the rear shocks one off the stiffest setting, all one-up riding.
I think if the mudguard is tight and correctly aligned there shouldn't
be any problem as it moves up and down with the engine/tire as a unit.
The Vespa tech that installed it said it was a sonofabitch job to get it on but.
1,950 out of a stock Pirelli is pretty good, probably a couple hundred beyond safe btw.
I changed out my first set of Pirelli's at 2,000, second set at 1600.
I couldn't believe how thin the center of the tire was at 2,000, man, I could stretch it out like a balloon by poking my finger in it when it was deflated.....scary.

Thanks for the reply marc.

It does appear to be very tight back there and with a wider tire, it would be very tight. Did you notice any top end or low end changes with the change in tire hight?

Any one else have experience with the tire?

thanks Kevin

In a word, no.
Just a more secure feeling on the road if anything.
If you want to go the way of better take-off and higher top speed a
slightly larger tire won't really do it.
There are a lot of options for you though.
The LEADER engine setup is very popular and well catered for.
The bug will bite
190 topend kit.
Malossi or some other performance variator (Polini).
Performance exhaust.
Performance shocks.
....and then if you still want to go 75 all day instead of 65 the Polini
final drive upgear kit.....(I wouldn't recommend that with the stock 150 though)

Hello,
Got my new Zippy1 tires on...I went with the 130/70x10 rear tire, only put on a few miles so far, but it appears to be a big improvement so far.
It does seem more stable, and easier to turn.

No rubbing issues so far with the rear shock on 2 (2nd softest setting).
No lowed speed loss and seems to have equal or slightly faster top end.

I would recommend this setup, as others have.
thanks Kevin
