alright mate, ive had my aprilia for 1 yr now and i have dun many miles. I havent had to replace anything in the engine due to a blow up or sesure!ive replaced the pistons and rings once as able to get one very cheap!!Even though people say that Aprilias are tempramental i have had no problems with mine 200 miles should be ok aslong as you put the right oil in the bike, do not rev the shite out of it remember its a 2 stroke! and fill the radiater up to the hilt!!good luke anyway mate!
