October 31, 201015 yr Hi all Since buying my EVO 2010 250,i have been made aware that the swinging arms develop cracks,is this correct?were should keep an eye on? Regards
October 31, 201015 yr I believe the problem was sorted before the 2010 models and have not heard of those with any problems.
October 31, 201015 yr That is basically what I heard. The '09 had tremendous failure rates for frame and some early swingarm. I have not heard of problems with the '10. The '10 frame has additional gussets and I believe the heat treating for the swing arm was improved. On the early Rev3s there was an issue where the swing arms were snapping at the junction of the cast piece at the front of the swingarm and the extrusions that make up the arms. Something to do with improper heat treating to relieve the stress caused by welding two dissimilar pieces together. What I also heard is that the Evo frame is not made by Verlicci as the Rev3 frame was so it seems Beta ran into the usual teething problems with the '09 Evo. Just in general keep an eye on any area where different pieces are welded together. One thing to note with an aluminum frame is cracks may appear in the anodized oxide on the surface. Though these can look disturbing they will not propagate through to the underlying metal. Of course that leads to the question of how can you tell a real crack early in its development and it's difficult without some very expensive equipment.
October 31, 201015 yr The swinging arm was changed during 09 and subsequently the 2010 had the stronger version ditto frame and rear brake pedal. There were not actually that many that broke, and it was mainly top expert riders who were stressing the frames.
October 31, 201015 yr Hi you'll be fine will the 2010 model, problems were sorted by then. I had an early 09 model and had two swingarms and a frame! But had neither on the 2010.
November 1, 201015 yr Lots of 09's sold in Canada and NO issues at all - maybe we got the later models.
