Maxsym 600i Tires and Rollers

Some items I have bought to be installed soon on my Maxsym 600i.
It is important to mention that the Maxsym 600i is currently having problems with oil consumption, it is quite nasty since I just rode about 1200 Km after the last oil change and I had to add 500cc of oil to get to the minimum level (Reservoir capacity 2000cc).
It is disappointing that an engine with such low mileage (currently 22.000 Km) is having this problem, the authorized Sym mechanic in my city told me that it is necessary replace piston and rings, of course...what? an engine with 20.000 Km on the clock?
So probably during the next months I will have to add around $700 USD for engine repair to the ~$600 I mention in this video.
