Tigerback Posted September 20, 2008 Share Posted September 20, 2008 Hi, My son has just bought a yamaha XJ750 trike and managed to hit a wall bending the bikes frame (just under fuel tank. Since its a trike we are not sure which model xj750 it is as the log book just says trike. can anyone tell us , if the frames on all the xj750's are the same? or do they all have different ones. the bike is a 1981 and it seems for the next 5 years there are many XJ750's but they have letters after the number and look different fuel tanks and seats. Any help would be apprciated. Link to comment Share on other sites More sharing options...
grizzlydan Posted September 21, 2008 Share Posted September 21, 2008 In most manuals you'll find a section on identification numbers (usually at the front), this section will tell you which letters or numbers will tell you what model & year that particular bike is from. Alternatively write down the frame number (complete) & ask a maindealer. Link to comment Share on other sites More sharing options...
Tigerback Posted September 22, 2008 Author Share Posted September 22, 2008 Thanks for the response, will try to check it out, but does anyone know if the frames for all the XJ750s were the same? as this would make the search for a donner bike easier. Thank in advance Link to comment Share on other sites More sharing options...
grizzlydan Posted September 23, 2008 Share Posted September 23, 2008 I would've thought so, considering the mass production & where the engine mounts would be. Then the same engine configuration (tuned however) should fit a variety of frames. Just like the early xj/fz600 engines that interfitted each other & also fitted into a xj550 frame, i had a xj550 like this & boy did it shift.
