Seem like every Vespa Grande bike I buy for restoration is of course plagued with a dried, cracked and ripped up vinyl seat. In the past I would shop on Buy Sell for a better looking option that when I got it in my hands can tell that the 40 year old seats vinyl was just a few ass plants away from also being split and cracked.
I had seen a vinyl kit advertised by for a while by Northwest Classic Seat Covers and finally decided to try one on my own personal bike.
It turned out so good and has held up so far for 6 months.

Here is a link to where you can get this same kit from Northwest Classic Seat Covers
Now here is the seat of the latest bike I scored and is going to be the precipitant of the new vinyl kit.

Most of the tools that I needed to install this seat cover kit are pictured below

Quality contact cement is an absolute must. I use this brand for all my heavy duty bonding.
I get this stuff in the paint section of Home Despot.

To completely remove the old vinyl it is necessary to remove the aluminum decoration strip. It is held on by three rather fragile threaded clips secured by 1/4 inch nuts. If you just start twisting the nuts of with your 1/4" nut driver the could break off. Pre spray the threads with some lube.

The passenges hold strap is held with m11 nuts and some fat washers. This one came apart nice because of the spray lube

This next step is important as it will make probing for the for the molding holes through the new vinyl easy. Using your eye, line up a sharp tool so you can scratch a reference mark in the seat pan that will align with the location of the moldings holes.

Since you pre soaked the threads with lube, your 1/4" nut driver will easily remove the fragile nuts

Gently remove moldings.

You will want to try to preserve the seat pans rubber edge welting. This will protect your new vinyl from the sharp edges of the pan.
