Modern Vespa

People are now weighing their tyres and rims? People are WEIGHING THEIR FUCKING TYRES AND RIMS?!

Recently mounted a pair of the Pinasco rims. I have 100/90 S1 tires on them. With the slightly larger tire size, I placed a washer on the hub studs behind the rear rim so the tire would clear the swing arm. I like the rims, and the 100/90 size. They give me a slightly larger braking surface. The hub studs were a little short with the thicker rims. I got lock washers and locktite to help my paranoia with the thicker rims leaving me less threads on the studs.

Moto Amore is selling the rims for a hundred bucks. This is a bit cheaper than I had seen them before. Thank you Euro for taking a nap.

And?

That's f-ing ridiculous. I just drank 2 pbr tallboys, there goes my power to weight ratio. Jayzus people, they're Italian shopping bikes.

I like going fast, ive spent way too much in pursuit of it on my various poxy hairdryers, but im not weighing my wheels.

Yes, drunkpost.

Yeah, next they'll be measuring their oil! Why don't they just buy Corollas?

I suppose one could practice bulimia as a permanence enhancement? Building a kitted motor and installing a lightened flywheel (search the threads) seems to be a popular thing, depending on who you believe. Reducing rotating mass from the wheel and tire assembly relates to the same line of logic, but if you're drinking PBR, it's doubtful you could understand. Considering shopping transports don't have efficient brakes, less rotating mass might also enhance ones ability to make it to and from the liquor store without incident? Drinking a quality beer might allow you to ponder things other than emptying your bladder?

Says the guy who owns:

1) modern GTS
2) P200
3) Stella

Your interest in quality seems to be focused on beer.

My P and Stella have motors built by Al Harpham. I realize you guys are neighbors, I'll be sure to tell him that you feel my bikes are junk, coming from the guy who constantly rants like someone on a Meth binge. Take your meds. You forgot to mention my helmet collection. Maybe had you been wearing one, you wouldn't behave so erratic?
BTW, I have 2 Stellas. Maybe I'll paint one pink and send it to you. Seems fitting

Well, since you think so poorly of Pabst and Pabst is from Los Angeles which is in California that means you think things from California suck. And since Fresno is in California and Al Harpham is in Fresno I'll call him and tell him you said he sucks.

You have two Stellas? That's even MORE hilarious.

Take your Meds

This is Chris on his meds.

Calm down. There was a time when scooterists had thicker skins.

Must be Willie's time of the month.......
Anyway, I was just looking at my rims deciding whether to weigh them. All of a sudden I felt a terrible twist followed by an almighty cramp in my stomach, forcing me to sprint like Hussain Bolt on crack to the wc.

10 sweaty minutes later and 2lb lighter, I decided not to bother as I'd inadvertently made my bike faster.

God bless you Mother Nature. You should work in a garage.

Resurrecting an old thread just to add my impressions on swapping to a tubeless setup.
I went from a standard setup to the Prima tubeless rims (same Continental whitewalls on both). The swap itself was a major PITA because it's so difficult to get the tires on these rims.


I only did this to get the reliability and peace of mind when touring, but I did notice a dramatic improvement in the performance, and I wasn't expecting it.
Don't know how much of it (if any) is due to reduced inertia, but there's a huge benefit from improved tire balance, reduced rolling resistance, and increased sidewall stiffness.
The bike does everything better on these rims. Acceleration, speed, cruising, handling, bumps... all of it.

I never would've thought of recommending tubeless as a performance enhancement, but after seeing how much of an improvement this makes, I kinda have to.
For those that are dubious, all I can recommend is that you take a spin on a bike that has had this done and judge for yourself.

HTHs,

I think it depends on what tyres you had before. I have been using TL tyres for several years, albeit with inner tubes, and did not notice a difference when going to SIP rims. If you are used to traditional TT tyres, then you may have a different experience.

I ran F.A Italia split tubeless on the 2016 CBR. They are each 1 pound lighter than the Pinascos and I think better looking.

Changing a tire is like 5 mins total I sold my SIP tubeless rims.

And how are F.A. Italia rims in comparison to SIP tubeless? I'm thinking about new tubeless rims for PX 150. With future plans for engine overhaul - with Malossi kit, etc.

Does anyone know if the pinascos come polished? Or do they only come black?

Since it's been bumped - and thankfully not for a discussion on meds:
- ScooterRaton - how have those F.A. Italias held up for you?
- Chandlerman - same question - any issues after your time on them?

Thanks gents.

I noted some of this in another thread, but four years on with the Pinasco's, I'm still running them and relatively happy with them.

The black anodized finish has held up just fine though sun, rain, snow & salt, and general mistreatment.

One of them has had intermittent problems with losing air, which I suspect has to do with the gasket between the rims, but that could also be user error on my part.

I had to replace one of them a year or two ago because a couple lug nuts came loose and pretty much immediately (less than a mile of riding) had oval'ed the stud holes too much to save. They are a little bit thicker than a steel rim, so on my Sprint, the studs could really stand to be a couple millimeters longer.

The replacement rim was an evolved design which dramatically eased getting the split together, but it's a tiny bit smaller on the inner diameter and needs a little bit of persuading with a dead blow hammer to get it seated onto the hub.

I would definitely endorse them, but for my next set, I'll probably try the FA Italia's.

I have probably mentioned this before as it happened about 8 months ago, but I had the rear wheel come off altogether with a Pinasco rim. The road was a bit bumpy and I simply didn't feel anything untoward beforehand.
I was fairly lucky (in the scheme of things) that the wheel jammed up in the back... the rear sort of dropped down and I skidded to a halt on the wet road. It bent every wheel stud and ovalled every hole in the rim. But the tyre stayed up!

I was a bit skeptical about the wheel nuts that come with the Pinasco wheels... they are a flanged nut that are serrated underneath and actually bite into the wheel. Now I use Nylocs and washers and sleep easier!

I wouldn't mind trying the split FA's... particularly as ScooterRaton says they are 450 grams lighter than the Pinasco's (which I think are about the same weight as the steel rims). They're a bit hard to find these days but I think Mercato has them... I also found these at a very good price at Duepercento

Just to confirm -- the Pinasco wheel came off because the stock nuts walked themselves off? That was the fault?

I ask because I'm getting close to pulling the trigger on a set of those rims. I just met a pair of your countrymen (that's you, Ginch) going around the world on a PX200 running a set of the Pinasco rims. And they swear by them, reporting that the only problem is you can only inflate them to 1.7 BAR when the wheel's not mounted, or the rim buckles a bit. After fixing the last 5 nuts though they apparently can be inflated all the way. Anyway, after their problem-free 40,000km two-up with luggage, I think the proof's in the pudding!

Thing is, I'm now married to 100/90-10's. And I'm not sure if those would fit on the Pinascos. And if I'm not mistaken those only come in 2.10 width, not the 2.50 width that some recommend for the 100/90-10's. Anybody out there have experience fitting 100/90's on to the regular sized rim?

Yep. Other than that I'm pretty happy with them. Bought another one to replace it.

I had serious vibrations through my frame on my restored PX that I rebuilt.
I put it down to the Pinasco 177 Alu kit. Even though I found the vibrations a real unwanted side affect at high revs on the open road.
As Rims I had chromed BGM rims with Schwalbe Raceman 3.50 x 10 tyres. I noticed they were quite wide and touching the clutch cover.
When i spun both the front and rear wheels both rims and tires had a slight buckle or sideways movement.
So Last week I ordered a pair of Pinasco Rims with Heidenau K80SR sports tires.
Amazingly compared to the Schwalbe Raceman tires the New Heidenau are 5mm narrower than the Schwalbe Raceman.
So around 2.5mm less close to the clutch cover.
Last night I fitted the new rims and tires and then run perfectly true with no movement like the old rims and tires.
I believe this was creating hugh amounts of vibrations through the frame.
I havent ridden the Vespa yet due to bad weather but I will let you know my conclusion.

Cheers Robbie

Hi jim ive been using 100/90-10 on the pinasco splits.
No problems.
However because the tyre is a little wider you do have to get a bit inventive and use longer temporary bolts to squeeze the rims together first before you can use the original short ones.

Thanks for that, Jim! Very helpful. My goal here's to get rid of that nagging paranoia about a high-speed tube blowout, without introducing a new nagging paranoia about a high-speed too-fat-a-tire problem. Seems like you've sorted that.

BTW with those Michelin 100/90-10s in the pic are you putting washers between hub and rim to offset the inner sidewall to the left a little and away from the clutch cover? I'm running Heidenau K80's and those tend to be a fair bit skinnier than other tires, so I might be in the clear. Just curious.

A Schwalbe Raceman 100/90-10 does not need any washers/spacers when fitted to the stock 2.10 rim, unlike others that I have tried eg. Heidenau K61. Maybe the same for a 2.10 Pinasco rim. I now use 2.50 SIP rims on my daily rides, with either 100/80-10 or 100/90-10 TL tyres. The 80 profile works well on my 150 Super as it somewhat de-emphasises the fact that I'm on 10" rims. The 90 profile is great for a PX and for a 5% upgear on my 225 touring scoot.

There's a motorcycle guy close by who does a great job of fitting and replacing tyres on the SIP rims.

Insider tip.
If you search "workmanship" on sip site - it brings up tire mounting...
Choose the tires (types) you want - and rims - and put 'em in the bin. Then search workmanship and add 1 workmanship for each tire you want mounted.
They will send to you pre-mounted with your combo of choice.

Mate im glad you brought this up as i was having that issue as well with standard split and later on with FA italia tubless.
I was forever shaving the clutch cover...yes...and the side wall of the tyre..crazy i know right!!
Out of pure luck or coincidence, the pinasco with the 100/90 no rub whatsoever.
They must have inadvertently introduced an offset in somehow manufacturing this rims..GREAT STUFF!!!

I had a very strange thing happen with a FA Italia tubeless rim; this one here: http://www.scootermercato.com/Scooter-Parts/Rims/5652

The tire was going flat and I could not for the life of me figure out what was leaking, so I finally put the entire wheel underwater and it was leaking from the actual rim itself. If you look at the picture, these rims have a decorative machined silver strip around the outside and it was literally leaking air from there over about a 3" section of the rim. They replaced it without question, but I question the quality of the FA Italia rims.
