First Ride on my 96 Pacific coast
Written by revconprince on 3/12/2012 at 05:45 pm

Yes, that is exactly what I am looking at. I fully acknowledge the torque
multiplication of the transmission, resulting in more force applied at the rear
wheel, when one can use lower gears. But if you are running the RPM up in a
single gear, the force applied to the rear wheel will be the same from 2000 to
6500 RPM. If you are trying to accelerate hard, you will run it out to redline
before you shift, taking full advantage running in a lower gear as much as
possible. In contrast, most motorcycles have a large blip in the torque curve up
in the top end, where if you are accelerating in a single gear, when you hit the
upper end, you feel a significant change in pull, or increase in pull. The PC
does not do that.

You have to be careful in how you interpret HP. HP assumes that the gear ratio
is optimum at all vehicle speeds. The only way for that to be true would be with
a CV type trans. Otherwise you are limited by the number of different ratios in
the trans, ie number of gears and how closely spaced they are. If you look at
the HP curve, you are assuming the power continually increase as the engine RPM
increase, but the reality is, you are applying the same amount of force on the
drive wheel across the whole RPM band unless you shift.

correct. The power curve is horsepower not torque. The torque curve is nearly
flat between 2000 and 6000 rpms but the power curve is a steady climb from 2000
to 6000 rpms with it doubling from 2000 to 4000 rpms, 15 to 30 HP, and
increasing another 15 HP from 4000 to 6000 rpms. Torque helps but power moves
the bike and the power needed to move the bike is not a straight line function
increase vs speed but increases as the square of the speed which the bike power
does not so the acceleration drops off as the speed goes up.

The power curve is nearly ruler flat from 2 grand to 6.5K. It increases by NO
MORE than 3 ft-lbs between those RPMs. Its got gobs of low end torque. While
there is some gain from staying in lower gears as a result of torque
multiplication, the bike has gobs of low end. Its not uncommon to roll the
throttle on from 1500 RPM in third or fourth gear.

I am sure that what I say here is not going to surprise any of the readers that lurk on this board. I am in essense, "preaching to the choir". I did a lot of research before I bought my PC and poured over many varied opinions. I am

      The brakes may get better with use. It may be safe to assume you new PC sat unused for a while. The pads may be hard and glazed, especially if the previous rider never braked hard. Secondly, you do have to get used to non-integrated braking a

    Ben, Try running 38-40 front tire pressure and 40-42 rear tire pressure, that seems to be the best on the PC and also on the Wings. Check your brake pads and see if they are Honda OEM, they seem to be the best on the PC. Many peopl

      It is not a good idea to try to ride your bike onto the tilted trailer when there is a 4 inch rise and you can't touch the ground. Said another way : Those 23 year old mirrors really DO explode when they bike goes down fast. Mirror housin

        The mirrors for the PC are one of the few "mistakes" on this bike....difficult to find and very expensive. I highly recommend Mr. Pacrat's modification. I think he has the finest mirror setup in the PC kingdom. I plan on

                Yes it is the Windscreen section. CMSNL has clear fiches for each year Pacific Coast. This is for the white 89 model. NH251P is the Pearl White color code. CMSNL is here in The Netherlands in the polder.

              Just as a follow up. Honda Canada had the mirror for $275 and it was backordered until at least May. Service Honda $200 + $15 shipping to Alabama $25 to repackage and ship to me as used parts. $240 total. Yes high but at least it w
