    ok no its not a rs frame, the er6 bike im building has a ZXR400 H1 frame modded to fit. The engine goes in after a bit of grinding and welding, the frame is currently getting painted at teh moment, but all the work is done. Rear eng mounts were re made, with exsisting front mounts used.

    Truth be told any commuter based bike, SV, ER, GSR, CB hornet etc is going to have a less than ideal frame. In uk the guys have done a CBR400 frame with a bracket that bolts the ER6 motor in, no welding required. But you'll always have some modifying to do.

    Ideal world for me would be a custom frame, if we see that the ER motor is the money ( which if we can get it light enough, it is ) and the modded frame i have holds it back, then we'll custom frame it.... i just happened to have a few ZXR setups good to go..... Aim to have it running for Tri series.... and it will be done well... trust me.

    Nice wee chassis that one! Best of luck with the build. Please post lots of pics as you go. I like stuff like that!

    no no what you need is one of these.

    one thing to always consider is the out and out hp versus weight versus the final packaging (is it high/or long or got fucked up weight distribution)....its one thing to build a high hp bike, or a lightweight bike, or a well packaged bike, but to be a winner it needs the right combination of all three. then it needs to be reliable and affordable (to whatever your budget is of course

    anyway i hope all these machines in the works come out to play in the future, the variety in the different approaches is sooo cool!!! A proper ER6, and a fischer 650 would be cool to have on the grid (even a hyosung made f3 spec could be a bit of a weapon - but isn't that just the fischer!!)

    That's damn nice. I wonder if the chassis is too stiff to get working at the much lower spec though.

    So the formula is ? : Take one ER6 motor, Breathe on it to find 10hp, make everything else fom unobtainium - & it might come close to a Tiggy (if well ridden)

    Looking forward to seeing the two RZ engined / RS framed F3 bikes currently being built make it to the track, wil add a bit more colour and smoke to the class.

    It has potential. It's ugly at the moment but it's a long term project so it should turn into something a special.

    There are a truckload of other options for F3, some more easily achievable than others. The cheapest and best bang for buck likely being the 125 with MotoX refit, Or an OZZY triple doesnt exactly break the bank either.

    Its one of the great things about one of the only 'Formula class" bike race series left. Personally i believe the rules should be ever evolving to allow scope, imagination and good ole fashioned No8 wire solutions..... However this thread is about the best donky 650 twin, should anyone go down that track. Looking forward to seeing / hearing Chappys unit + hopefullly a few more.......
