I never said any such thing. I rarely ever use the top half of the tacho.

That is precisely my experience of inline 4s.

No kidding. My blackbird and my jap sports 1000s all have way more bottom end
than my DL1000. In fact getting off my CBR1000RR and onto the Vstrom makes
the V feel positively gutless.

Don't buy a Guzzi then. They get their jollies at the higher end of
their rev range.

No torque is the right word, it just sounds like you've not compared
engines lately.

I own a late-ish model litre twin, I love the way the engine performs
and sounds, but it has by no means the low down grunt of the 4cylinder
it replaced. The only real difference between it and a brand new
current litre twin would be a smidgen more top end at the expense of
even less bottom end.

The reality is even the tuned & modified version of the Raptor (TL1000
motor) I have only has a 110 RearWheel HP (stock is about 10 less- 125
at the crank claimed) with about 105Nm of torque at the crank claimed
(don't have my dyno chart handy to be able to tell you what mine
actually has at the rear wheel. A litre 4, even one 10 years old has
at least as much (1999 R1 crank claimed 150 HP and 108 Nm for example)

The current model 4's have more all round (the GSXR1000 is renowned
for it) and the current twins are giving away torque to get HP up top.
Sure if you compare a 1200 twin to a litre 4 it's about even.

Ie 2009 Ducati 1098R - claimed 180HP and and 134Nm, 2009 R1 claimed
180hp and 115Nm and yes the 4 has it's peak higher up the rev rang
(10K vs 7K) yes 20Nm is noticeable but 200cc you'd expect a little
more bottom end and the longer rev range tends to make the fact you're
revving it harder not very noticeable

Are you talking about 2000 or are you talking about 5000 (which may be
"low down" on a 4 but is almost redline on a big Harley)?

I can't even FIND a 4cyl torque-curve that has figures below 3 (which is
what; 30kph over the city speed-limit in top?), but according to these
they seem pretty similar from 3,000 to 5,500.

Not really a fair comparison though; the CBR should probably be compared
to a big BM, Ducati or a Norge (I can't think of any big Jap twin
cruisers) and the Vstrom should probably be compared to a Z1000 or
something a bit milder.
