Leeds?

I'm quite capable of deciding for myself how much of the available
power I want to use on any given occasion without some wanker at
Hinkley deciding that because the bike hasn't got a fairing I don't
want to use the same amount of power as I would if I was riding a
Daytona. **** them and **** the Japs who do the same with their naked
bikes.

 

Ah I'm with you now, it's the same engine as other models but de-tuned. Yes
that always pisses me off too, like the Fazer Vs R1 etc. Kawasaki just did
the same with the GTR Vs the ZZR1400.

 

why do they do it, anyway?

Even the B12 is detuned from the GSXR1100 that the motor came from.

 

Something to do with charging £££ in other models for the few extra BHP?

 

Andy Bonwick says...

The Daytona and Speed Triple engines are not the same. Different
cylinder blocks with alloy liners and lighter pistons are on the
Daytona, and the Speed Triple gets more conventional items along with
softer cams. Tuning a Speed Triple to give Daytona power output is a
very expensive business. You'd be better off buying a Daytona and
stripping the fairing off then sticking it on eBay, cos brand new
Daytonas are cheaper than 2 year old used Speed Triple 955is at the
moment.

Really!
The conversion isn't straightforward unfortunately

It's cheaper than buying a used Speed Triple.

New Daytonas are out there at £5700 OTR, I even know of a black one at
that price. Converting one to '04 Speed Triple looks isn't difficult or
expensive once you've sold the bodywork off. When I lived in Worksop I
saw a local mate do a T509 Speed Triple conversion to his crashed and
written off T595. That was bloody simple and cheap using mainly new
genuine T509 parts.

what about the new Speed Triple? I was going to ask if it were the
same engine as the new Daytona, but there doesn't appear to *be* a new
Daytona apart from the 675.

There's not going to be a new big-bore Daytona, from what Triumph are
saying. For a nuber of reasons they don't want to enter the race with
the big 4 for the best litre sportsbike.

It's often quoted like this, but in practice the mid-range gains are
often almost non-existant. I recall testing a 955 Daytona when I had
the 955 Sprint and not noticing any lack of oomph lower down the rev
range. Then again, I couldn't really say the extra 15-20 horses at the
top end were particularly noticeable either.

As will it's more powerful brethren. Modern litre-bike engines have
just got _so_ much poke throughout the rev range that 'tuning for more
mid-range' is an absolute nonsense. The gixxer, for example, will
literally pull from tickover in top gear, and it doesn't even feel
gutless doing so.

Needs? What you talking 'bout? You can never have too much power.

Ok, I'll phrase it differently if it keeps you happy.

To make me want to buy a Speed Triple it'd need at least as much power
as a Daytona. Tuning the Speed Triple to make the extra power may well
be expensive but building it from new with the same engine wouldn't
cost a substantial amount more, especially if Triumph have got engine
parts left over from the Daytona that need using up.

The extra power on a full fat litre bike makes them easy to ride and
they generate that power right through the rev range. I've had my bike
on a dyno, seen where it's making power and it's a straight line
through from the bottom of the rev range to the limiter for bhp with
the torque curve tailing off a little earlier.

 

Only if you choose to use the extra power. And if you were to use it
then surely you must be getting some benefit from it.

Rubbish. Unless you've suddenly turned into a hamfisted fuckwit, any
decently-fueled bike will allow the same fine level of throttle
control, regardless of how much power may be availabe at wider
openings.

 

Of course, we'd both be wrong because we've not got 180bhp to play with, but
like you, I'm happy enough with the ~120 I've got. Sometimes *too* happy.

Where do you get this idea of 'less power at low revs' from? As I
thought we'd discussed earlier, modern sportsbike engines develop more
powere _throughtout_ the range than their detuned emasculated
brethren.

You're back on the meds aren't you. He's talking about the Zed.

It's a pussycat below 3thou as you say and it's one of the things I like
about it. I can switch off from being "biker boy" blasting around like a tit
and not even bother changing gear as it'll pootle along quite nicely in 6th
gear at any posted speed limit and below. Strangely enough, even *we* have
to stick to the limit on occasion.
