    Honda want to save us from ourselves.

    Possible stability problems with the oe panniers fitted iirc.

    I see by mondeomans post you don't think it is, go test ride a VFR12200f, or just read it's spec , the bike they took the engine from to put in the CT, and then post your opinion

    Theres no doubt the CT is down on Power and Torque on the 1200F, however to use the term "restricted" isnt really how it is.

    Its not simply been a case of tweaking the ECU to restrict power (though that can be done). The CT has been tuned to have different characteristics to the VFR, probably with different cams and inlet lengths for a start.  Its all about compromise. The requirements for a bike like the CT are different to those of the VFR.

    I found this rather useful comparision on the interweb.



    The red lines are the CT the blue the VFR.

    The VFR figures really start to pull away fron the CT around 6500 to 7000 RPM but the key thing for me is the other end of the graph.
    The CT is nearly making its full torque at a lowly 2500 rpm. At around 3200 RPM where the VFRs trace begins the CT is making around 25% more power and torque.

    I do get where youre coming from, if Honda had just stuck the VFR engine straight into the CT itd have numbers to rival KTM but for me at least, in real world riding, give me the grunt at the lower end anyday.

    So would it be major surgery
    to regain some, if not all of
    the engines performance,
    that's if it is possible at all??

    My guess would be it’d easier ( and no doubt cheaper) to get hold of VFR1200F engine and install that rather than convert a CT engine.

    But why bother? For all the hassle and cost you could have a second bike.

    Same/similar V4 motor/engine plant for both motorcycles with different electronics, tuning, exhaust and etc...
