I would say that most of the motorcycle/scooter manufacturers have exact knowledge of how a motorcycle/scooter has to be constructed and built in the 21th century.
But for some speculative reasons some still decide to do otherwise.
For example unfortunately DEALIM fled the USA market some years ago, but they have some real clever engineers.
Luckily they are still in Europe.
I give you an example with some details:
The Daelim Otello FI 125 ABS 2017 from South Korea is a good value (€2.500,-), easy for maintanance, pretty well constructed and built scooter. With some clever details. Maybe not the most beautiful on earth, but also not the most ugly.
4-Valve Euro4 FI 125cc engine with 12hp.
Oil cooler.
A 9,5L gastank for some good miles a tank.
A clever tank cap with Key access and flip mecanism.
Easy to access snap in covers for brake reservoirs. Both front and rear.
Bosch ABS braking system front and rear.
Oil level check glass on the left side of the engine block. No dipstick anymore. Oil refill through valve cover.
Service cover for valvecover and valve lash check.
Two oilfilters. A rock strainer and a real oil filter cartridge.
Good seatfoam and quality material for seat cover.
Easy access to battery and fuses underneath the seat.
Large trunk for an integral helmet.
Good access to lightbulbs.
Hazard light function.
Muffler flange to exhaust pipe, so for a tire change only the muffler has to be removed and not the exhaust manifold.
Easy to access strong passenger footpegs and easy to replace in case.
Also comes with some nice standard accessory as sissy bar or windshield with handprotectors.
Digital display with tripmeter and digital fuel gauge.
Top speed 105-110km/h.
Another nice scooter of Daelim would for sure be the new Steezer model. And nice price also.
If I had´nt already the Like 200i, I now would definately consider these two as a sincere alternative to Kymcos so called "better than best" products...
Sorry for my comment this time being so off topic.
