2017 RS dyno result

[itstuantran_imp]

Look like the specs specified by Honda was not aligned with what has been dynoed or the way power measured is different! I did not have chance to have the stock setup dynoed but for sure it's way lower than the number publicized by the manufacturer

Mine is 2017 RS with Motogear header (Cat free) and BMS R-evo muffler, K&N air filter, TSR air intake, ZFI Bazzaz...
First dyno without tuning:87,9HP
2nd dyno with tuning: 89.5HP

Still not removing speed limiter so it stops at 180km/h

Manufacturers measure horsepower at the crankshaft, which does not include losses from the rest of the drive train. The dyno measures power at the rear wheel, which does include the losses from the drive train. As such, a dyno run will usually produce lower numbers than those published by the manufacturer.

I've seen several dyno charts for the stock bike and they averaged around 82-83hp peak power at around 7,300 rpm.

Thanks Flyrinder, good info on stock power. So with the new gears, around 8hp gain over stock.

for me is much more important how evenly does the curve rise....our CB is in this way just super...

It would be nice to test the bike from stock with no mods. Otherwise, we can only guess!

How do you know your intake performs better than stock?

[itstuantran_imp]

As Flyrider mentioned he saw several graphs of stock dynos around 82 - 83Hp.

Yes, but you need to compare apples to apples (same dyno) or you'll be just guessing.

[itstuantran_imp]

Yup, it should be apple to apple for better comparison but i did not have chance to do that. For actual performance, it's quite a clear response in all RPM range as i'm using it to commute daily so the response felt quite clear.

By removing the stock dual exhaust, which weighted 15 kg and replaced by full titanium system with 6 kg, a net save of 9 kg will definitely boost the performance, not mentioning to and free cat header will help boost much better, K&N air filter and TSR air intake, cooped with bazzaz tuning, it really transformed the bike . It's not the guess only

did you get torque #'s? I'd be interested in seeing those.

[itstuantran_imp]

Unfortunately the tech guy could not get the signal for torque, i'm also excited to see those too. In fact, i can tell a significant pull from 3k RPM and above compared to stock
