Both scoots are easy to DIY service. I would not own either of them if they weren't!
12 months of riding my 2012 LIKE200iLX:
@ $15 +/- for > 3 oil changes, one gear oil change, one new airfilter, one valve adjustment.
One flat tire by screw in rear Michelin P. Pure - repaired at home with plug kit.
Averaging @ 70mpg with Shell Super.
12 months riding my 2018 Piaggio Liberty150i:
@ $25 for > One valve adjustment, 2 oil changes, oil filter change, one gear oil change, one new airfilter, fitted longer puke tube from a Kymco.
One flat tire, screw front Maxxis, repaired road-side with plug kit & electric pump.
Averaging @ 97mpg with Shell Super.
Neither scooter had a crash, nor a part failure. Other than flat tires - all servicing was preventative rather than "fixing" something.
In other words, both EFI scooters performed flawlessly again this year. Neither tire "Mushroom plug" is leaking.
