As high mileage motorcyclist I have purchased 10 new maxi scooters, over 400,000 miles on them, since 1990--still keeping motorcycles.
Biggest problem when you ride a lot----head BUFFETING!!, followed by sometimes uncomfortable feet forward riding position.
List: Four Helix, 175,000 miles total, liked foot brake, rear "car trunk". All four, all the same things broke---air box, intake stub.
Belts could be changed without taking clutch apart. DANGER: J rated (62mph tires) on bike that would go 67-70 mph downhill-tailwind. Had one Bridgestone fly apart in motion (in Japan).
Reflex, destroyed at 22,500 miles by woman on cell phone as she hit me from behind at stop---ins. totaled-----maybe better bike than Helix...still used easy way of valve adjust.
Burgman 400(2)--after 2007 type=probably more comfortable ride than SilverWing in spite of great unsprung weight on rear. Likes:4 way flashers, various gauges, 60 mpg. Problems: #1 had engine case defects oil leaks at 8,000 miles dealer took it back as trade on TMAX. #2 at 20,000 miles drive train...clutch, belt, etc blew up near Suzuki dealer in Dalton, GA---Suzuki paid for everything, including new belt. I like riding under warranty!!Rode it to about 40,000 miles.
SilverWing 600 (2)---near 90,000 miles on these 2, reliable, dated, hard ride, very sensitive to tires (make and their condition as they wear).. BUFFETING with GIVI adjustable shield. Way overweight!
TMAX Yamaha---almost forgot this one making 11 maxiscooters
Fast, good handling, more important fun to ride----at 16,000 miles traded as I feared high maint. costs as it aged. Would try another if still on our market.
Daelim 125----last time in Korea= great! never broke, with 125 no belt issues, wide open 65mph, not overweight, enjoyed it with the Daelim 360 degree strong bumper, Daelim top box...had to get Puig windshield to block the breeze.
So: Helix my favorite to use.
SilverWing vs Burgman 400=Burgman nicer ride, 4 way flashers nice for old fart who has to stop to pee a lot, 100 lbs lighter, still heavy. SilverWing=too heavy, top heavy feeling at rest, reliable.
Scooters need to come in brighter colors...=nice to be seen
Next for me?? another Suzuki TU250?...in spite of no centerstand? Not another SilverWing 600. Vespa? Not cheap, no dealers...BUT can be made buffet free. Had 4 of them in past.
Stay tuned----my present SilverWing approaching 50,000 miles and time to go soon.
Note: I make no mods on all other than: NEP throttle stop/top box/some times sponge grip over covers---think monkeying with drive train waste of time. Reg gas, in US Walmart10-40 oil, Fram filters. OEM drive belts!! Tires: this time IRC Honda recommended, this set has lasted 15,000 miles!--wear like iron, hard ride, rear wears SQUARE, making difficult handling....car tire people probably wouldn't notice the rear, when it is worn.Tues. new Michelin Power Pure SC on rear/replace burned out low beam -----no electronic add on my bike, tried plug in for heated bib----took off. Always carry paper maps....Depend on feathers to hold heat in, in cold. Had electric vest failure in northern Mexico=almost froze to death, put me in $150 Motel to get warm.
