So,
I have an Aprilia climber 280, i bought it a few months ago and its a bit tatty!
I have replaced the kickstart lever, the brake pads, the gearchange lever and the rear shock. I will be riding it again soon to check if it was worth while or not!
I got the kichstart lever and gearchange lever from Andover Norton - they were really helpfull and matched my old parts up in no time at all!
The pads were from wemoto - although took 2 months to arrive (although i blame the post not them)
the shock was an ebay item but again i was lucky to receive a tidy item!
im quite new to trials so i dont have any wonderful hints or tips for the Aprilia crowd but im sure there will be far more knowledgable people than me in here!
All the best
