I 've an old, but alive and kicking, XT600 1989' (2KF)
Time has come to rebuild it. The motor is over 120000km, oil get vanguished very often and kick compression has become piece of cake.
Unfortunately, I must also replace the main frame-chassis of the bike. The main left side tube, that joins the end of the backbone, is bent by a massive crash with a car. The check 'n' straightening procedure by the appropriate electromechanical tool (that I don't know the exact word), is too expensive. It will cost me around 250 euro and although it will be in a straight line again, it will always be a repaired frame.
In our "ebay" days there are so many bargains. So, I 've found some very nice restored frames (powder coated) for less money, than my engineer asked me to repair my exhisting one. I am looking forward to buy one of them and replace my old, rotten and bent one. Problem is, I am wondering if I should buy an original "XT600" one (2KF), or a "TT600" one (Belgarda). Not the "TTR" 1998 with the Paioli forks. The previous one from 1993 (I think) till 1997 produced. With the Kayaba upsidedown forks. Specifically a white frame, by a 1997 TT-600E (electric).
Both seems in very good condition and it's up to me. I have to choose one.
Finally. I think I 've noticed, that the tube's thickness from the XT600 (2KF), is bigger than TT600E (Belgarda). I am not sure! Suppose, by what I see in the pictures. And knowing that the TT is -theoritically- more Off-road, it should be lighter -->> thinner
Anyway. Does someone nice guy
, could tell me if there is significant difference between these two frames, in matter of "stiffness"? Weight? And lastly, geometry?
Thanx in advance and 'njoy with the Great Yamaha Thumper
PS. I have some more questions, considering front-end, swingarm, shock and some engine tuning, but for later. For now, I have to solve this puzzle and buy a new "house" for my bulletproof engine
