Torque monsters?

Hi all. So anywhere between the next month and year or so, I'm planing on getting a big bike. I ride an 85 Shadow 700 which I love, but I want more low RPM grunt.

H-D is pretty much out of the question other than maybe a Sportster due to $. But I need a bigger touring bike than a Sportster.

What bikes pump out, but most torque at the lowest RPMs? I don't care about HP. It's all about torque!

I know for the ULTIMATE torque monster is the Boss Hoss 502! That thing would be my dream bike! Not Hayabusa fast, but it has the torque to snap out your shoulder socket! No better feeling [not the snaped collor bone part though!], but obviously I don't have nearly the funds.

I'm really leaning towards a used Roadstar 1600/1700 Silverado. They supposibly produce there 99 ft/lbs of torque at just 2,250 RPM! That means it pumps out tons of torque just off idle. It redlines at jut 4,000 RPM too! But has a nice tall 5th gear, and you'll never see redline in 5th or you'd be at over 165 MPH. Love that big air cooled pushrod 30's technology motor too! And its one of the best looking bikes IMHO. I can afford a used one at $3,000-$5,000 for an earlier model.

Its not JUST abotu torque, but about low end torque to me. Low HP and high torque can be fun for some. Like a Roadstar Radiar 1900 cc and the warrier. Those only have similar HP as a H-D, but all the power is the torque! Won't beat an R1 but it'll feel faster.


But I wander why they don't just go to diesel with some of these type bikes! They can produce much of there torque at low as 800 RPM! Many redline at just 3,000 RPM and under. You'd likely wind up with one slow bike, but extremely torquy at all low RPMs. You could cruise down the freeway at 1,300 RPM with a big inch diesel engine in a cruiser. wack the throttle and it'll just pull harder without ever touching the gears. It would also likely get better MPG's, as seemingly diesels burn a bit more efficitently and it's spinning at idling speeds. In some places diesel is cheaper too. Just a thought it'd be cool.

I know there is some diesel bikes too. But I think most riders seem to care only about Horsepower, and hi revving. But some of us love that torque! Like a V8. Yea 4 bangers can be tuned to pump out more horses, and be more efficient, but nothing beats a V8!

My 94 F250 has a 460 in it. I love that torque! It'll turn at under 1,500 RPM in 4WD up the steepest hills when I'm offroading, and not need to downshift when I hit it, just pull harder. I can only imagine a bigger engine, the 502 chevy BB, in a 1,300 pound motorcycle!

VTX1800 has a lot of torque and turns about as well as a boss hoss
Victory puts up bigger numbers too (~100) and they actually have a bit more ground clearance

100lb/ft isn't that much though... I've got 110+ and meh! I'm pushing a land barge. 130 would be a lot nicer I'm done trying to make this thing go faster... it's a losing battle.

nwdub the triumph Rocket III sounded promising when I first herd of it.

BUT, 2 issues for me.

1.It turns at higher RPMs than I had hoped for on the freeway.

2. Its not no V-Twin.

That Vulcan 2000 is promising! Claimed 142 ft/lbs at 2,800 RPM! And WOW! It seems to be capable of pumping 116 HP at 5K! Which means it keeps it's torque thru a wide RPM range! 2,053 cc ain't bad!

I do like the Vulcan a lot. A great looking bike! Only issue is the $ for me. But this discussion ain't just about the bike I'm buying. Its about torque monsters expensive or cheap!

I'd definitly qualify the Vulcan as a top torque monster!

The Rocket III definitly! I just wish it was geared taller. 5th gear is only 62 MPH and already at 2,500 RPM!


trc.rhubarb I like the VTX. BUT, it likes to rev to much, due to the Dual Crankpin design. HOWEVER we's also gonna quality it as a Medium RPM torque monster, it pumps out 120 ft/lbs but at 3,500 RPM. HP is at 86 HP at the wheel or 106 BHP. Not bad!

Heres the list so far:

Low RPM:

-Roadstar 1600/1700: 99 ft/lbs @ 2,250 RPM
-Vulcan 2000 142 ft/lbs @ 2,800 RPM
-Rocket III 2,294 cc 147-165 ft/lbs @2,500 RPM


Medium:

-Honda VTX 1800 120 ft/lbs @ 3,500 RPM

I got to ride one of these.....


Been riding 45 years, ridden almost everything there is to ride (except a Bimota ), and I have never, EVER, ridden something that hits this hard in 1st, 2nd, & 3rd gear.
Ride one & you'll want one!!!!!!!!!

For cheap torque, you want the Suzuki VS1400 Intruder. . . . It doesn't have the big torque numbers of the other bikes you're listing, but it doesn't cost the big dollars either. 'Course 88ft-lbs. isn't anything to sneeze at.

All that torque and hydraulic adjusted valves, too!

If money is no object:

150 ft-lbs of torque and 132 HP.

if it's not to late the RS Warrior is an excellent bike for a big twin.

on the VTX1800
Two front disc brakes = 1800
One front disc brake = 1300

Honda screwed up when they stopped making the 1800 and used the 1300 on the Fury.

Guess the 1800 scared the shit out of too many people. It runs with Goldwing both 1800s.
The Wing is more of a Mochine, the VTX is the torque monster.
Also, it does tend to drag footpeg feelers in the twisties.

Torque Monster for the Twisties

OK, this bike has no where near the peak torque of the recommendations above, nor can it match the torque of a large displacement Ducati, but it handles a lot better than you'd expect and the motor - with the monster low-end torque combine with the lack of an explosive higher RPM - just made it uniquely capable of shredding tires through the tightest of twisties, just off the low end.



Been riding for almost 4 decades, almost exclusively twisties, and have never before, or since, been able to consistently wear out rear tires in the sides before the centers....clicky

(too bad HDs are so unreliable)

That wimpy Rocket III only comes with 163 ft.lbs from the factory.

Torque at the wheel = (engine torque * gear ratio) - transmission losses

High rpms implies high gear ratios

Hmmmm....

Really, have you ridden an R1?

Think about this, a 502 making 500HP in a 1300 pound bike is .38 HP/pound. That is HP at the crank, so it is "generous".

The R1 is what 140HP and and under 450 pounds wet. Right about the same HP/weight ratio. And you could pick it up if you dropped it!
