Edited Date/Time:
18 models. Six trials bikes, four minis (including an MC-E5), four full-size MX bikes (125, 250F, and 450 F), and a slew of off-road models.
Confirmed that TLD will handle the team, racing in both the 250 and 450 classes. Tyler Keefe will continue his role as Team Manager. No rider announcements as of yet.
There's a new website, http://www.gasgas.com/ (last I checked, it was struggling). Maybe give it a bit.
