Newbie tech question: why/how does Honda Fury make low power?

Discussion in 'Motorcycle Racing' started by Billericay Dickie, Aug 21, 2010.

  1. I know this is a racing forum, but seems to be mostly
    swearing ---.

    Looking at the specs for the Honda Fury chopper, I'm puzzled to see a
    modern motor, with 3-valves per cylinder, fuel injected, overhead cam,
    of a massive 1,300cc capacity --- produce just 59bhp.

    You'd think a Boy Scout troop working in a garden shed, if they
    cobbled together a motor with those specs, would see more power. Did
    Honda engineers have to work hard to REDUCE the power --- an odd task
    for a m'cycle engineer?

    Does the motor run on just a dribble of fuel to get "good" mileage?
    Polite explanations welcomed. Cheers.

  2. Don't you think 59 bhp is more than enough for anything as evil-
    handling as a chopper? Plus it's unfaired, which limits how fast you
    want to travel, and the tyres limit how fast you want to accelerate...

    I did a quick gwgl but couldn't find; what revs give max power
    and what torque/revs for max torque -- that will tell a lot.

    They're just emulating Harley.

    You're right, this is a racing NG

    The Rebel, oops, Fury, is a CRUISER. Therefore it's aimed at a market
    who likes whatever it is that's appealing about cruisers, they
    probably don't care about high power output or fuel consumption.
    Cruisers with big cc long stroke air-cooled twins are about image and
    low revs.
    If it made twice the power what do you think Honda'd have to change ?
    (that's rhetorical).
    Seriously, I think it's a great looking bike, but I'd have the MT-01
    or the new V-Max if I wanted something a bit different.
