The TU250 is a good bike, but costs about $2000 more than the Wolf. You can actually buy a Wolf OTD for $3000, but by the time the Suzuki powersports dealer gets through adding things on, the TU250 will be about $5500 OTD. That's for 2012. The price went up for 2013.
For comments from actual Wolf owners, check the SYM owners forum. Most of their complaints seem to be about cosmetic issues, but poor quality paint, plastic, and rubber parts does not bide well for the quality of the mechanical parts. SYM scooters seem to have none of these issues, which leads me to believe that SYM does not have any say so over quality control on the Wolf. The Kymco Agility 125 is also made in China, and I have not heard anything bad about it, cosmetic or otherwise.
