montman Posted October 31, 2010 Report Share Posted October 31, 2010 I believe the problem was sorted before the 2010 models and have not heard of those with any problems. Quote Link to comment Share on other sites More sharing options...
dan williams Posted October 31, 2010 Report Share Posted October 31, 2010 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.

nigel dabster Posted October 31, 2010 Report Share Posted October 31, 2010 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. Quote Link to comment Share on other sites More sharing options...
duggan Posted October 31, 2010 Report Share Posted October 31, 2010 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. Quote Link to comment Share on other sites More sharing options...
outlaw dave Posted November 1, 2010 Report Share Posted November 1, 2010 Lots of 09's sold in Canada and NO issues at all - maybe we got the later models. Quote Link to comment Share on other sites More sharing options...
