SYM is a Taiwan company that competes with Kymco. They have been making bikes since the 50's as well as cars and bikes for Honda and cars for Hyundai. there is a new distributer in the US that is doing a very good job. They are in fact where my Canadian dealer is getting his SYM parts these days.
I have owned 16 bikes over the last 44 years and so far after 11000 miles my SYM Citycom has been the most trouble free bike I have ever owned. My back tire was still looking pretty good at 15000 km but I picked up a nail so it was time. The stock brake pads were cheezy, the front lasted 8000 km and the rear 15000 km. EBC organic pads improved braking greatly. My fronts now have 10000 km on them and are 25% worn.
The original battery was an el cheapo and after two years it was time. I swiped the Yuasa AGM battery out of my DL1000 which fit and now the bike starts instantly. It's way cheaper to run than my big bikes and good for long day trips. I doubt I'll ever buy another big bike.
