    The Bros (Hawk-GT in USA) is a little known gem that can still cut it with the best in the twisties.
    It has quite an Internet following:

    Welcome to the forum RC31. Hope you enjoy it here. Like you say, the RC31 has got quite a following out there. Drop us some more info in the members’ bikes section if you get chance.

    Like you site RC31, you clearly love your bike. Am I being thick or did the NTV650 share quite a bit with the RC31? This was probably on your site, but I read quickly as I should be decorating right now!

    The RC31 does share some common parts with the NTV650, like the majority of the engine, although in a ‘slightly’ higher state of tune.
    In standard trim it only puts out about 50 horses but the grunt… just roll open the throttle from 2k RPM and it doesn’t hesitate.
    Other main features are,
    All alloy frame instead of steel.
    Chain drive instead of shaft.
    Alloy single sided swing arm (a la Ducati).
    Different character altogether and much more ‘sport bike like’.

    It is reputed that Mr Honda took an old RC31 and dropped in an over-bored/tuned XRV750 engine to develop the VTR1000.
    An XRV750 bolts straight in and is an often used mod on the RC31.

    Mine is pretty well sorted now with a CBR6 F2 complete front end (bolts straight in), modded ‘blade rear shock and VFR750 rear wheel (minor mod to Bros spindle).
    It really does handle well in the twisty stuff and will easily keep up with modern sport bikes (my mates ZX9 can’t get away from me) – until the straight line bit when it’s lack of horses shows!!
    The simplest way to gain some performance is to remove the boat anchor of an exhaust collector box/muffler and replace it with a ‘free flowing’ can and then put a 0.75mm thick washer under each carb needle, put the front carb main jet in the rear carb and a slightly larger one in the front carb, tune the carbs and there you go…

    Cookeye has noted at how well it handles in stock trim, as it is only 180kg all up, low centre of gravity etc etc.

    Love the swing arm on those things, a work of art. Does it handle OK? Friend of mine has one and says it is great unless you get into a very tight bend and then it starts to bounce around a bit. Told him about your site by the way.

    Oh yes it handles real now, and allows for errors that lots of bikes these days wouldn’t let you get away with.
    Mr Honda sold it short with it’s original setup (parts from their spares bin probably). Modifying it really does improve it when you chuck it about in the bends, which is where this little gem excels.
    Never had a bad ride on it, just waiting for the sun!!!
