hi all this is my first post and hoping to get a little help from you all. recently took the plunge and decided to get back into trials after an 8 year absence(well no bike really )and thought i would give the four stroke a go so bought a new montesa 260 4rt 2015. really happy with the bike,runs like a dream but when i was cleaning it a few days ago i noticed what looks like a faint hairline crack on the front top engine mount. i phoned the dealer and emailed a photo to let him see,but when he got back to me he said all of the new models in the shop have the same mark and it must of happened in the manufacturing process. so my question is,do you own a 2015 4rt and does yours have the same mark on it? many thanks
