Modern Vespa

Has there ever been talk of the GTS 300 (or whatever the next GTS will be) going to 13-inch wheels? It seems with any meaningful power increase (such as with the 2019 23.8hp model, etc.) it may be a smart move. Would 13-inch wheels degrade the aesthetics/design flow of the 300?

Here's one I made earlier
13 inch front and rear
You decide:)

Beautiful! Looks a great bike, 13" wheels or not.

The only problem as I see it is getting the special wind you need to go in the bigger wheels. Ordinary stuff is no good! I take it you can obtain the special wind ok in Scotland stage2? I've heard there is a lot of wind up your way.

Jet, I don' think Piagigo has ever talked about fitting 13" wheels as standard, and I personally don't think they need to go there with 24ps. Mine is smooth enough at 70-75mph, but undoubtable 13's would be a bit better.

In my opinion, the front wheel cowling/fender is a bit small with the 13" wheels. If I were a Piaggio designer I think I'd want to make it a big bigger to accomodate. Other than that no issues.

Your scoot really does look great! How do the larger wheels effect your ride/its performance?

Special wind we have in abundance up here- usually coming over that piece of volcanic rock you see in the background.
Performance /handling wise , I cant really say i've noticed much of a difference.
The wheels are off a Gilera and are 130 front 140 rear- its a Malossi 218 and is good for 82mph on the GPS, but most of it is town riding so not really utilising that.
Aesthetically , it has a Mudguard/ Fender ( depending on which side of the Atlantic you are) extention from SLUK which basically catched most of the crap thats thrown up onto the underside of the body normally

The 13" look great! I wish Piaggio would adopt them for the 300 GTS.

My principal concern would be with the lower profile: depending on the setup, the ride is likely to be at least a bit more harsh. Looks nice, though.

I do have a stock GTS to compare against.
It has a top box and bar weights on it , but cant really notice much in the way of harshness between the two.

The black GTS is a 13 model, my other one is an 11 model, and , to be fair, the 11 saddle is more comfy, even at rest, so its not exactly comparable.

Living in Edinburgh, the roads arent exactly Autobahn standard

Here's a picture of one of the roads on my daily commute- it closes to traffic between 10 am til midnight.

There was no adjustment on the rear wheel correct? Other than messing with the shock.

I've been thinking about spending the money to change my 12 inch for the 13's on my 2011 GTS. It's got a top case and bar weights. I like to ride her at more of her top end speeds and would like to have the larger wheel base.

Is it lower as someone mentioned? I wouldn't mind as my 29 inch inseem, I can flat foot when I lean on one side but have trouble flat footing both.

No adjustment- straight on.
Again comparing to my standard 11 ,it feels higher.
As I said tho, the 11 is 'plusher' on the rear end -think its the saddle tho and i'm sinking in more.
I've got a 29" inseam as well and weight 90kg

It's worth noting that the Gilera Runner wheels above are 3.5" wide, where as all other 12" & 13" wheels that fit the GTS are 3" wide. I think that the wider wheel and lower profile flattens out the tire's contact patch, which could limit the max lean angle. Realistically it's not an issue though, as the center-stand and body already limit that...

Here's some more info & pictures:

Well... all except this... not 100% sure it will clear the trailing arm though.

... probably one of the reasons it they don't make it any more

What 13" options are readily available in the US for the GTS 300? It's a change I would consider.

Paul

+1 on this.

The speedo's off already, so what the heck.

Yes.

I looked into it and scooterwest has 13 inch rims (And Tires). I saw a video on youtube of Robot talking about the rims and tires. That's where the idea formed.

Roughly speaking it's $100 for the rim and then the cost of the new tire. So, not including labor, around $400 to upgrade.

Now the idea of the 13.5 inch also intrigues me as it is wider. I like to ride 45-55 or higher and with the topcase and barweights, I'd still like a bit more stability at those mid to higher end speeds.

Everything is available in the US if you can find someone to ship it. I'm in California, and was able to get Gilera wheels from SIP shipped direct. Here are some Piaggio 13" wheels that should fit (I'm not 100% sure about the Italjet wheel)

If you run a 130 tire, the speedometer is closer to reality. The 130/70r12 is almost the exact same height as a 130/60r13.
