This Information Power to Weight Ratio Motorcycles: Comparo, Read More

A collection & comparison of the "Power to Weight ratios" of the "Made in India" motorcycles.. in 2012

How “fast/zippy” a motorcycle feels (particularly in which part of the rev range) depends on various factors like

[1] How the Power is spread across the rev range
[2] How the Torque is spread across the rev range
[3] The Weight of the vehicle
[4] The Gearing on the vehicle (tall geared or short geared)

By comparing the “Power to Weight Ratio” of various models, one can get a rough idea of how the bikes stack up against each other. To compare our "made in India bikes" by their "Power to Weight" ratios, I have compiled a list posted below.

In 2012, the KTM 200 Duke has emerged as the bike with the highest power to weight ratio in India (among the Made in India motorcycles) followed by the yet to be launched Pulsar 200NS. Both the 200 Duke and the Pulsar 200NS beats the Honda CBR250R which had the highest Power to Weight Ratio among made in India bikes in 2011.

Although not a "Made in India" model, for those interested about the Ninja 250R; with 33 Ps of Peak Power and 172 Kgs of Kerb weight it has a Power to Weight ratio of 192

How Power to Weight Ratio is calculated?

In simple words by dividing the “Power” by the “Weight”, we get the “Power to Weight” ratio.

To make sure that each of the various models can be compared, one has to make sure that the unit used for “Power” and “Weight” for all the models are same. In the list compiled above the unit for power has been taken in “Ps” and the weight in “Kgs”. Also for all models the “Kerb Weight” (which is the Dry weight of the vehicle + 90% filled up with fuel and engine oil) has been taken into consideration.

Power (in Ps) / Weight (Kerb Weight in Kgs) = Power to Weight (in Ps/Kg)

But since the number obtained in the above calculation is very small (in decimal points), the above formula is multiplied by 1,000. Which is also equivalent to dividing the “Power” by converting the weight in “Tons” instead of “Kgs”.

Therefore..

[Power (in Ps) / Weight (Kerb Weight in Kgs) ] x 1,000 = Power to Weight (in Ps/Ton)

P.S: I have taken care to calculate the max. power in "Ps" and the “Kerb Weight” of each model into consideration in the calculation. Kindly point out if you come across any blooper from my side in the above calculations and also in the max. power / kerb weight figures.

You can also point out if I have missed any current model from the above list.
