Is the TC more 'Grunty' than the WC

Rode a TC for the first time yesterday and it felt very 'Grunty' more so that what I remembered from a WC ride a few weeks back...

So is it?...
 
No, i's just that the WC is deceptively quick. The twin cam is still a nice ride, though.

I agree, the wc revs faster and gets upto to speed quick, where as the TC don't, so you than feel the torque of the motor more so.
 
Absolutely not - the LC does 40-120mph in 13 and a bit seconds in top, so has far more grunt :thumby: I'm constantly looking for 7th gear as it pulls from much lower revs than my GS MU and RT TC
 
The Fonz says it's all in the right hand

Most dyne charts show the TC stronger below 2,500, beyond that they're similar up to 4,500-5,000 (depending on the dyne run) where the TC develops a dip in power and the WC keeps on climbing. I know when cruising at 4,000 around (70 mph on a TC, 73 on a WC) then downshifting to pass, the WC pulls *much* harder.

I am new to the WC and still learning and I LOVE it, BUT am ashamed to admit that I stalled it and it fell over a week ago, whilst pulling away on a very slight hill. :eek: I felt a complete muppet: I haven't stalled a bike on tarmac for years and years, perhaps ten years; it's what you do as a novice! My last bike was a single cam 07 GSA.
The WC has shed loads of power and torque, but how much is there at or around tick over ? Is it less or a lot less? Perhaps I was just careless, but its knocked my confidence and I'm about to tackle the Alps. No damage btw, stopped dead and rolled over gently :D
 
The graph shows the old GS has more torque and power in the 2800rpm range used at starts and the lower end of the rev range I used when bimbling about on back roads. I now ride in gear lower with a few more revs, the positive advantage of this is the throttle response is so much better. The engine is in a much better state of tune and on a 600 mile through the Northern boarders returned 65 mpg.
I came across a beautiful biking road skirting the top of Kielder to Carter Bar on the Scottish border, no traffic, undulating with some superb bends and twists, it's on these roads where everything on the LC works and comes together.
I was only revving to 5500-6000 (approx. 80 bhp on the graph) but the new engine does not have the power hole the old used to bog in. Loved it.
Its obvious to me the magazine road testers use the bike like this and that's why they all rave about the engine. I have only seen one review on an American youtube review where a dirt bike rider preferred the bottom end power of the old bike.
 
I found the WC less tractor and revs a lot faster but did not pull from low revs as hard in higher gears more than likely the lighter flywheel effect.

I would imagine in the alps in a tight uphill hairpin when you are one gear to high the old tractor will be more forgiving and the WC will be just more fun getting to the next hairpin :D
 
The WC is far 'gruntier' than the TC - I found it much more reassuring in the Alp's hairpins when two up than my old TC which I often felt was on the verge of stalling - the WC just picks up the revs and powers out of the slow tight corners.

Which one has more grunt under 2,500 rpm i.e pulling away speed? ( I need to think about this i.e. what rpm do I use when just pulling away gently)
 
Short answer NO

Just off tickover i think the old bike might have been a smidge happier, just a slight perception. Not sure if the new bike runs higher gearing? that split second at the bottom of the rev range? Overall the new bike is much gruntier though, way less vibes than the old one too, i think theyve got it spot on with the new engine.

Hey Paul

You should have bought the RT mate.....the hill start function is magic.
I'd totally dismissed it as a gimmick, until i had to stop on an incline to fix my visor.

Stop, select neutral, flick the front brake lever, feet down, hands off the bars, sort visor, select 1st, open throttle and away.....

BTW, i also stalled the new GSA when i tested it :blast. It just seemed harder to launch than my TC...:confused:
Oh, and i also stalled the new S1000R (twice). And i haven't stalled a bike in many years.

Just looked at the graphs from Hilltop for my old tractor and its about 68 ft/lb @ 2500 rpm and go to 70 ft/lb by 3000 rpm peaking at 80 ft/lb at 6500 rpm the bhp is now flat without the big hole and peaks at 105bhp @7500 rpm I don't know what the non optimized TC will on the same dyno be or the WC
 
Yonkyo, your pocket summary is a good description: "harder to launch" fits in with my assessment. It flies when launched, but at a traffic light grand prix,it is harder. Is that a function of engine, or clutch or gearing or all? The WC is a licence taker and its so very smooth at speed The RT is surely still at the top of the world as a touring bike btw.

Don't know the actual figures below 2,500 but I can pull away in second on the LC without much clutch slipping.
