    I second that.

    6,500 at 100k in top but around town I probably sit at 6,000 in 4th (or 3rd??) or if i'm stuck behind kapiti drivers about 11,000 in 1st so they take notice and do over 30kph, and if they dont I'll pass them. some times i just do 58kph (according to the courtesy radar) at about 3,500 in 6th and wallow around the place. especially along the beach

    I just ride everywhere between 8 and 13 krpm.

    I don't *have* a torque wave to surf.

Plus he was poorly attired for motorbicycling, and when cranking it around a sharp left, he showed he had poor technique by keeping his head lined up with his body, rather than keeping it level and looking through the turn.
    I suspect he knew I was behind him, and was showing me he was better than me. Yeah, whatever, Mr Knob-End...
    He sounds like tha average K.Ber!!! however it's trouble making Jappa riders like you that cause grief & bother by 'pressuring' others to try and impress you!!!
    If you had managed to catch up with him you could have pointed out the faults in his riding style.

    And it goes without saying that as a H-D rider he WILL have ginormous 'nads, he has to have them to cope with the H-D flak flying in his direction.

    Most motor will love to run at their maximum torque rpm,they settle down nicely,you can roll off the throttle and maintain that speed easily,they can pull well from that rpm too.But if your bike is in a higher state of tune ,it's going to be screaming a bit.The XS650 Yamaha I don't even take to max torque,I short shift,doing 4,000rpm to 5,000rpm,never above or down,with a smooth riding style the thing can keep a good pace.My TS400 was the same,this was geared high to hell and gone again - I just rode it 3,000 to 4,000rpm and could keep a good speed no dramas.

    What your bike has torque as well!!! You're dead right Jim. Horsepower is great but torque makes you move. I once knew about all this stuff from my time studying 1st year physics, but now I've forgotten.

    Oh, come on, it's not that bad.

    Torque is twisting force. Different engines create a different amount of force per revolution at different speeds, depending on design. Think about it. That's the reason for the torque curve. Any engine will have intrinsic inertia, balances and resonances and all that stuff that makes it create more force when cycling at one given rate than another. Big singles make a lot of twisting force when turning over slowly, but don't work well if you try to make them run fast. Formula 1 V12s don't make a lot of torque per cycle, but are designed and built so that they can run at very high speeds and still generate force with reasonable efficiency each time round.

    Power is the total work output capability of the motor, which in this case is twisting force generated by each engine cycle, multipled by the ongoing rate (measured in, say, revolutions per minute) of complete engine cycles.

    You'll get more power, in the end, from an engine that continues making a reasonable little bit of torque through very high cycling speeds than you will from an engine that makes gobloads of twisting force but only while it's cycling under 4000 revolutions per minute, for instance.

    I third that, only its the CBR F1 sound that turns heads.

    Come on now mate, your just showing off. But you are right. Differing engine configurations have different power and torque characteristics. That's why I still prefer singles and twins for commuting.

    Stuffed on a race course, of course. (Now about those World Superbike rules..)

    19,000? If I could get my Sporty to do that in 5th I would be doing 360mph (550kph+), - 205mph? - pifff! small fry!!

    Rubbish! I watched "Top Gear" on Sunday night, and he reiterated what we all are aware of:
    No-one actually knows what torques are, except that it's good to have a lot of them installed in the engine bay.
    ... and that's what I think.

    Or summat.


    Or maybe not...

    Dunno really....

    if the sporty did 19000 in neutral it would be a miracle!

    If the sporty did 19000 rpm the piston would shoot through the head at 360mph....
