Hiya researching 749/999 frames for a possible project seen a few diff types some with adjustable rearset points, some not, some have oval swingarm pivot others are round also seen some with extra braces across the top anyone know specific differences year to year/model to model? are they all the same geometry materials and weights? i know that theres lots of different adjustable stem/yoke/steerer configs, but are tall the head tubes the same thanks in advance
basic model no headstock adjustment.. multiple rearset agjustments on all except R models that only have 2 for homologation frame braced on genuine rs frames or added at a later date….
The oval hole on anything other than an RS was for show only as the engine on all road bikes have a single hole through them . RS have an oval hole in engine cases to allow swingarm adjustment . The R frame has a couple of pieces that are bolted on ,as opposed to welded ,to allow for quicker access .
