Hi, i have the same bike, aprilia climber 280. Parts are a nightmare to get, another thing is they have a poor kickstart knuckle so you need to keep tightening it, i take an allan key with me when i use my bike. the bike uses a rotax engine, and any parts needed for the engine can be got from the rotax man, http://www.rotax.co.uk/, who will post any parts you may need, also priced reasonably. the forks have gone on my bike so i am currently looking for some. They are a good bike but as you said, parts and info and few and far between, great bike tho. hope that helped a little
