Modern Vespa

Oil cooler? Or what?

Unless it has a fan behind, I can't really see much air flowing through that oil cooler in that location under your bum and behind your legs...

Love the black/blue combination...

Odd, that. Would like to know more about this.

(I took the liberty of changing the title, since "A cooler on a sprint" made me think this was another discussion of mounting things to the rear rack).

Where are the engine connections for the oil lines?

Sort of like the bodge used on early CB750s.

Another approach.

Love it!

The oil cooler is placed there to keep your legs warm in winter.
I actual made a vent in the service hatch were that oil cooler is hoping my lx125ie would vent a little warmth with my apron. It does a little when driving slow.

I've been to Seventeen Garage in Bekasi. I went there even before I found my LXV.

If only there was a translation 🤷‍♂️

But in general: lol

That thing of replacing Plastic parts with Carbon Fibre (most likely fake) is stupidly expensive and ain't gonna help.

It's like the CNC Aluminium parts to replace plastic 🤦‍♂️. Stupidist is the Zelioni bag hook

It says Zelioni. Your gang colors + that = instant street cred. I have replaced a few plastic panels with Piaggio Faux Carbon Fiber parts. Usually they are cheaper than the part in the correct paint color, and you can touch them up with a sharpie. Sadly, the bike didn't go any faster.

The person with the oil cooler has punched the Sprint up to 200ccs, so the extra oil capacity and cooling probably does help.
There was, and might still be, an oil cooler kit for cars that had a spacer that went between the spin on oil filter and the engine, with plumbing for an oil cooler (basically two places to stick a hose. The idea is that the oil goes into the filter and then the cooler, and then back, or into the cooler and then into the filter, not sure which. They were easy to install. I could see making something that would replace the spin on oil filter, with holes to stick a couple of hoses to, and then running it to a PGO Bubu/Genuine Buddy style oil cooler, that has a place to screw on a Piaggio oil filter. That would fit just about every Vespa/Piaggio/Aprilia with a Piaggio 125-300 engine ever made. Someone could make an initial run of 5000, and all six of us in the world who think it's a good idea would buy one.
If you haven't seen it, and I didn't until today, gridoto.com has some pretty interesting Vespa Sprint modifications. Google translate is good for about 80% of the words.

Hi would this lot work ..looks like possible male to female adapter needed to connect to engine and 12v supply

The Genuine Buddy 170 has an oil cooler, if I remember correctly.

Thanks Syd for that .. just checked the expo on that ,the engine is different by the looks of it ,so the oil feed is different..the oil cooler on its own would work but still need something like above to feed it in an out

I doubt it. The Sprint 150 oil filter sits in a recess. The edge around the recess would prevent the adapter plate from sitting flush on the engine case.

Hi its not for a sprint but a gt

I haven't considered a cooler but I have been looking into oil temp monitoring

was considering something like this on the oil pressure sensor

or maybe SIP's solution to stick the sensor in the drain plug like this. Although this is for their speedo, could probably use a regular (aliexpress) sensor + display with the same drain plug

I think the sip electric racing (might be malossi)rev counter has a fuel, water temp ,oil temp aswell but over £120 plus ..
After the state of this engine will need as many dials as possible lol

No question, the Buddy's engine is quite different the a Sprint/Primav/S50/150. But the Buddy has an oil filter, implying one "could" be installed on above.

Syd ..its for a gt not sprint and I assume you mean cooler not filter..
If you look at the pictures I have put up then you will get what I'm on about..

here's the deal, essentially you need to do a remote filter and integrate a cooler into it. the hang up is that there's basically zero-point-zero room at the filter location, which is where you'd tie in at. and it doesn't matter if you're doing a GT, ET or sprint or whatever. the basic architecture is the same.

also, there is not, to my knowledge, an adapter plate on the open market. which means you'd be making one; hope you have a machinist friend who works cheap.

so let's say you whip up an adapter, now you're faced with the problem that you only have so much room for your supply lines. which means you're likely cutting the case and moving the exhaust OR them supply lines are gonna be tiny.

then you'll need to mount the remote filter and cooler. that's trivial, though.

the other possibility, I suppose, is that you could do circulating system, which I don't love. you'd need to pick up pressurized oil off a port in the case (pressure sender probably) and then either tap it back into the system thru a drain back galley via the case (plug) or you'd punch a hole in the sump and drain it back into there with a restrictor, maybe, probably.

but again, you're talking pretty small lines. so most of the capacity is going to be the cooler. which, with all that you'd be lucky to see a 1/2 quart increase.

the filter adapter is the correct way to do it. the other way will work, but that's some real amateur hour garage goblin kinda work.

personally, I think increasing the sump capacity would be a better approach. beef up the cooling system considerably as well to keep the heat in check and run absolute god tier level of full synth oil and it should live.

What's considered 'god tier'?

Hi greasy, I'm looking to go down the 1st route you mentioned, getting some sort of adapter made ..luckily my friend has a machine shop and he's prepared to let me loose in there lol.
I've already spoken to him about making a custom headset for some custom drop bars ,will break this extra news over a beer lol..
I was planning on mounting the cooler by the radiators but awaiting on some gilera forks to turn up to see how much room left ,then running hoses under plastics

depends on your religion.



motul 300v should suffice

better make it a steak dinner with nice wine!

I highly doubt there's enough room under the plastic work to get anything up by the radiator. or at least anything substantial enough to make a noticeable difference.

The water pipes run under the plastics ,so was hopefully going to follow the same route. Will mean enlargement of hole and new grommets..
Next problem is exhaust in the way of oil filter if protruding out too far..
Solution..re run exhaust to come under the floor with side exit (possibly removing side stand) ,which then will leave room for a belly pan, (px style)
Yes lots of work in no hurry though
