single vs twin vs four

I really enjoyed my two V4 engines from Honda . But I have been a fan of the Vtwin ever since the Hawk GT650 came out . But due to the price I never owned one . My current ride has the 114 Vtwin motor . Suits all my needs at this time .

I drive a diesel truck, my tractors have all had diesel engines, I have a 17 ton cummins powered excavator :|
do you seriously expect me to be inspired by the torque of your motorcycle, it ain't happening.

... my ride of choice is a trials bike, my street rides are just for slaps and giggles.

What exactly does that have to do with bike engines ? I drive diesel powered trucks and buses for a living too so what .

have to agree. Stay on target Mr. Trials!

I know what torque is, I know how to use it, I know enough about engines to know you can increase a motors torque characteristics just by bolting an extra 10 pounds on the end of the crankshaft if it doesn't twist it apart.
torque = work
horsepower = wow
The rest depends on how well they bring it all together in the form of a motorcycle.

... three cylinder 4-cycle works real well in a sea-doo!

HP is an expression of torque over time

to get an idea of how an engine performs you need to look at a torque curve chart

diesel engines are better at not lugging down
do you know why? and it has nothing to do with torque values

nope
that's not it

read up on crank throw mechanical advantage
cylinder pressures and injection cycle timing

better at not or better at,
how would you have me read that and relate it to actually operating a diesel?

... diesel's have a speed that they operate particularly well at,
and that has a lot to do with a slow burning fuel in an engine that is operating under roughly twice the combustion pressures as a gasoline motor.

it's says not

you claim to own some diesel engines and talk about towing
this should be something you understand

and I'm done trolling you
trying to turn over a new leaf

I don't really have a preference. I've owned singles, v twins, inline 4's and a V4. All of them were entertaining. Some of you are a little dramatic about the low end of inline 4's. Downshift or twist the throttle harder and any of them can pull hard if they are performance type engines.

Downshifting completely defeats the purpose of low end capability....:rolleyes:

Can't say i agree or we have different ideas of what 'pulls hard' really means.

Well part of the conflict likely comes from comparing engines of different sizes. I was amazed about how little thrust a 600 SS had down low (and how much up high). The closest displacement V-twin I rode was a wee strom. If those were my only two options for a daily bike, I would take the inline four as I found the wee boring everywhere in the range (for an expedition I would take the wee though).. I have never ridden a one litre SS, so I may be wrong about my idea about low down torque, but I really really like the way 1000 to 1200 cc v-twins feel on the road (~100 to 150 hp).

Not if your in the completely wrong gear and then want to complain about the low end. To experience no low end try a 125 mx bike.

Bikes I've owned that I consider to 'pull hard' Tuono, ZX6R/GSXR600, KTM 450 supermoto, KTM 625SMC and YZ450. My Harleys didn't pull so hard and neither did my DRZ400 but that was a fun bike too.

Wrong gear is relative. I don't want to ride around with my bike screaming look at me every second I'm on it. Sure, dropping down a few gears when an interesting stretch of road comes up is no problem, but most riding in Ontario is boring cruising to get to the next interesting spot.

Is wet and slippery as all heck out there right now by the way,
but still fun. I use second or third gear mostly on a wet day like this :| everything I ride around here is interesting.

@GreyGhost let's pick a 600 ss. Cruising around in 2nd or 3rd at 6-7000 rpm (in my opinion we're in the low end here considering the bikes rev out to 15,000 plus rpm) and you crack the throttle the bike will still have pretty strong acceleration yet the real power comes on well over 10,000rpm. If your poking around in 6th gear at 3500-4000 rpm then yeah acceleration isn't going to be great.
