Just looked at a 2021 Kymco AK 550 in a showroom. Interesting. Sharp looking. Felt substantial and solidly built, although the passenger foot pegs and parking brake control were definitely Tinker Toys.
It had 14" tires, decent storage under the seat, two small glove boxes (so small I'm not sure what they are designed to hold. My hand?). No electronic screen. No tire pressure readouts like the BMW. I think it has ABS, definitely has two disks in front. Dealer said he could sell it for "Nine grand, maybe $8900." He also said they were hard to get ... "Only 32 were shipped to the U.S. and I got two of them."
Maintenance looks simple from online videos (plenty available) and it was easy to find a free pdf of the Kymco Service Manual. I downloaded one in case I need it some day.
My current ride is a 2013 BMW C650 GT with 18,600 miles. I got it with 15,100 miles, updated the maintenance and it's run like a Swiss watch. As long as it's trouble-free, I'm happy to see how far it will go. I know riders here have put on 60,000+ miles with no troubles. If I switch bikes, I'll go with a newer BMW C650 GT.
BUT ... since BMW stopped production of the GT, making it extinct like Suzuki's Burgman 650 and Honda's Silver Wing, we maxi-scooter afficianados have to keep our eyes open for future rides. I'd say Kymco's AK 550 is worth a good look.
