Thanks Big Done guess I owe Dr. Neels Vanik a very humble apology.
His software was spot on once again.
Can you tell me the RPM for peak power and Torque.
Ps: The loss would be more than 15% remember you have have two chains.
Most bikes have only 1.


Max Torque  @ 3500 rpm. Max HP @ 4250 rpm. Per the MCN article.

wooooo
No matter what the looses your peak power and peak torque RPM numbers cant be wrong.
Which basically means the company provided numbers are pure BS.
Which is on par for most Indian companies.
I really feel cheated. 1.5 Lakhs is not a small amount for most of us.

Did they say what Dyno was used.

How can I buy this article ?

Does anybody have the Dyno numbers for the Cast Iron 500 or the AVL 500.

After such a glaring mistake on the part of RE Im SHOCKED to see people whine and moan about the price quoted for an oil change. Dont you think the disparity in power output is more critical. Than the price of Oil issue ?

The feeling I get is most of you guys would still buy this bike if it made 2 BHP and had a top speed of 20 Kmph.

The dyno tests of stock iron-barrel models show about 14-15hp at the rear wheel with the 4-speed gearbox(grease-filled), and about 15-16hp at the rear wheel with the 5-speed gearbox. The 5-speed gearbox has lower transmission losses.

72Westie did a dyno run on a new Electra X AVL and it had similar power level as the iron-barrel, about 16hp at the rear wheel.

Both of these engines can get up to about 20rwhp with a free-flow exhaust and carb re-jet.

The stock iron barrel peaks hp at around 4300rpm. It peaks torque around 3300rpm.
Those peak rpms go up by a few hundred rpm, in both torque and hp, with the better exhaust and new jets.
I don't have those figures for the AVL.

72Westie also ran a new stock UCE on his dyno, and got about  21hp at the rear wheel. I don't know what the rpm was. I do remember noticing that it had a very broad torque curve. Each engine will vary a little bit in dyno results, so that would account for some difference in the MCN dyno test, and 72Westie's dyno test.

So, those are some real-world figures that are actually seen at the rear wheel on a dyno test.

Here are some dyno runs of all three engines. These came from the factory.
I am guessing that it is at the engine although I can't state that with certainty. One problem with dyno's, especially dyno jet dyno's, is calibration in relation to each other.

 FYI
1 kilowatt = 1.34102209 horsepower
1 newton meter = 0.737562149 foot pounds
