Go to 21:30 and watch for about 20-30 seconds.

OK ... now what ???

I was wondering what everyone thought. Looks pretty slow to me. Revving it all the way to the redline seemed to resulted in just keep up with the Yamaha escort bikes.

IMO, sounds like a Harley with a potato stuffed in the muffler and didn't seem all that quick.

It is hard to tell acceleration unless there is a HD in the mirror......

Correct!! Haven't had a H-D in over 10 years (Thank GOD)

Is it me, or does it look like a 4500rpm redline?

TwoWheelObsession on YouTube test rode one too, and had commentary. He said the rev-limiter kicked in at 4500 rpm, even though redline is 4750. Anyone know what the redline is on the older version of that Yamaha motor? Seems really low. I think my 1100 had a redline of 6500.

The rider in each video said the rev-limiter kicked in harshly, too.

They said the motor had decent power between 2500-3500 rpm, but otherwise felt flat.

Another comment from TwoWheel is that the motor got so hot that he couldn't touch the fuel tank with his leg. It was 96 F, in Florida, and was an urban test route.

...that why it's called the "Transcontinental"

It has to accelerate across the entire continent to get to speed :shhh:

Yamaha did not release the HP numbers, but being a low rpm air cooled twin, it probably has around 75 ponies. Divide that by its hefty 950 curb weight (I don't think that is wet weight, either) and you get a power to weight ratio of about 13.0 hp/lb....pretty similar to my wife's V6 Kia Sorento.

F6B is about 7.5-8.0 hp/lb, depending upon whether power at the wheel or the engine's output itself.

I think your numerator and denominator are backwards. :icon_wink:

Whoops. Boy, that would be one fast bike...

[bigdawg]

According to Rider magazine article it has 76.9 hp on the dyno at 4500 RPMs.

The majority of riders that buy this type of bike really do not give a "rats ass" about fast it can go in the quarter mile , etc., They want pulling power, torque at lower speeds, and decent passing power riding two-up...So most of this conversation is a "moot point"....JMHO

:icon_rolleyes: you're entitled to your opinion, but I am going to have respectfully disagree. I am sure there are some who don't care, but obviously there are a lot that do as evidenced by this thread, by the magazines that do dyno and 1/4 mile runs in their tests ,and by the conversation about such things I see on Facebook and other Forums.

If that were true, there'd be no such thing as Screeming Eagle stage 1-4?. Victory had all types of stages 1-3?. Power commander would be out of business. Very few of the V twin riders I know have no motor mods. Seam pipes and air cleaner are the starting point.

I still take exception to the above opinions in most cases...Too many of you nay-sayers are comparing "apples to oranges". Most riders that put all these Stage 1,2,3,4, kits etc. on Harley's Vics, etc., are looking for a little more power and sound and these riders are generally not riding full blown touring bikes...I,e., Honda GW's, BMW, 1600GTL's, as they make sufficient power stock form...I am pretty sure Yamaha did a very thorough research of this market with this big heavy tourer, as they have many years of experience with "hot-rod" bikes that scorch the 1/4 mile....Regards

I moved to the F6B precisely for the reason stated above. I had a couple Roadstars all outfitted for touring (fairing, stereo, custom front/rear suspension, hard bags, etc). Love the sound. Just couldn’t get over the highway vibrations (those are probably fixed with this new Yamaha) and most importantly the lack of power, especially at highway speeds. I’m a die hard Yamaha guy. Love the sound of their v-twin motors (unlike Honda’s v-twin motors which sound terrible).

I’d like to ride one of these (Eluder most likely-what a stupid name). If they could make it have the same power as my F6B, I’d likely go back to Yamaha. Don’t think that’s likely though.

I’ve toured all over the eastern US on air cooled, belt driven v-twin bikes. Those aren’t negatives IMO. The lack of power is the biggest issue. I probably have close to 100k miles between all of my Roadies. Belts can go 100k+ miles easily. Air cooled motors from Yamaha can also go to 200k miles with very little maintenance (oil changes like anything else). They almost never even need the valves adjusted. Plus, when you smell coolant burning at a stoplight in traffic, you know it isn’t you.

HP and TQ numbers on a bike like this are a big deal to me. Maybe not so much to other guys, I don’t really know. What would be even more important (to me) is a comparison with 1/4 mile times, roll on from 60-80 or 60-90 or so, top speed, etc. Real world performance type stuff.
