I took a chance and bought a chromed plastic peak for my Vespa scooter. It has held up perfectly and looks just as good (to me) as the expensive metal versions. It comes ready to install with its own 3M double-sided adhesive tape. I'm probably going to get one just like it for my 2013 Royal Enfield Military and paint it either black or OD green.
What year is that Vespa? I bought a brand new
'09 Genuine Stella, an Indian made copy of the Vespa P series, and the last year for the 2 stroke, and have has no issues at all with it at just past 10,000 miles, other than a top end seizure at under 300 miles, probably trying to ride too lean during beak in during 120 degree Phoenix weather.
Over 4 years ago, I found real Deltran Battery Tender Jr.s on sale from Dennis Kirk, free shipping, and bought 5. I connected the leads directly to the battery, then stuck thm out from under a sidecover or some other place they would fit through. My Stella battery died, but it was a cheap flooded lead acid battery, and I threw away the Enfield battery for the same reason. Every time I park a bike, I plug the tender into it. When I go for a ride, I unplug it, when I get back I plug it back in. I have the connectors laying right where I park the bikes. They work fine on any flooded battery, or any SLA AGM battery. I see the AGM batteries as being the best thing out there right now. You used to could buy a quality flooded battery, back in the '80s, Yuasa made great ones. Now all you can get are junk. Some people had acid damage from them, I never did on a new bike. But they had to be kept filled (and not overfilled or underfilled, and you had to use an acid catch tank on the vent hose. The AGM battery is just a better way. but they work well enough, and last long enough that I see no need to try using something like a lithium battery. Just heard about to many problems. The battery on my one year old laptop is already down to 73% of new capacity. And I constantly unplug it and let it drain, then plug it back in and charge it up, just the way my computer guy says.
