Looking to pickup my first trials bike here in the next few days. I current ride the woods on a ktm 300xcw, and I race downhill mtb's in the summer full time so I plan on using this bike as mostly a training tool, and to have some fun trail riding in the woods with from time to time. I am not planning on doing any competitions or anything like that on the bike because the DH racing takes up most of my free time and weekends. So a little about myself, 5'10" 185lbs, athletic build. Been riding woods bikes for the past 18 years, along with a fair amount of road riding, and I race in the expert class on my mtb. As for the bikes, it seems I am limited to a newer small bike, or an older bigger displacement bike. The bikes currently in my running are a 2013 sherco 1.25, 2005 sherco 290, and there is a very slight possibility that I might be able to afford a 2012 gasgas 280 eco. I actually got a chance to ride a 12' sherco 125, and a 12 gasgas 280 yesterday, but it was very limited test ride, and the 125 had some MAJOR custom gearing on it with a 59t rear sprocket! So I plan on using this bike just go hone my skills a bit, and my wife also just got into riding, and she has an xr100 she is learning on, so I was planning to follow here around on the trials bike instead of the 300 just because i think it might be more fun for me. Any thoughts, suggestions, or useful words of wisdom? I would say my max budget is around 4k, but i would obviously be happy to spend less. Any advantages/disadvantages to a smaller vs larger, and going new vs old on the larger/smaller bikes...any major geometry changes, or ride changes? Thanks!
