Exactly, I can only guess that you are correct, either it is their 2010 that they tested on their dyno or they got the numbers from somewhere else. I know there is no way a stock Road* is putting thoses numbers up. I'm not sure if we helped out the original poster or just muddied the waters even more.

My 05 dynoed 75 HP 98 lbs TQ with the OEM carb I don't know what it gets now with the HSR 45. And that is with the Bub Stubbies the TQ would go up with a 2n1.

I dynoed my stock 07 with only an exhaust change on a Winpep 7 Dynojet. 78.96*F, 29.54 in-Hg, humidity 45% and got the following results. Max Power 52.25 Max torque 87.28. The same time we dynoed my bil's 06 fuel injected Road King and he got around 94 hp but only 50 something torque. Now we really got the water mudied up.

Boy, those numbers, both for your '07, and your bil's Road King really don't make a whole lotta sense.

Your HP should have been considerably more, and his hp less, and torque more!

Something is wrong with your 07. It comes out of the box with about 63HP and 95 TQ. My 07 with stock rejetted carb, Bak and 2-1 exhaust is 75 HP and 100 TQ

Yup, sure enough, there they are... 87 hp and 107 torque. Certainly not factory specs, so must be there own dyno findings on a 2010 they tested.

Just seems so high!

Some of you fellas dynoed your bikes. You ever roll up numbers like those?

Really makes NO sense. The numbers on Yamaha's own site don't even come close.

'99-'03 1600s are 52 hp, 87 ft lbs.

Wow..my 03 only has 52hp? 1600cc's? That's embarrassing. Guess we can quit making fun of other brands.

Ya gotta remember the HD has a higher compression engine than the R*. That will make the HP higher with a smaller displacment.

Ours weren't engineered for HP, but for tq, which is why they first ran out of breath, and was limited to 4,250 rpms.
