The Cast Iron Engine in Royal Enfield.

The Cast Iron Engine in Royal Enfield bullet Series.

So, the question is what is the cast iron engine?

Well the answer is so clear as Cast iron is a metal type and Royal enfield used to made their engines from casted iron so they known as the Cast iron engines.

In this engine the whole assembly of the engine was divided into 3 parts are as follows:-

1)- The Internal Combustion Engine(piston and head and the area having crankshaft).

 

2)- The clutch assembly

and

3)- The Gear Assembly.

Due to this the engine became heavy and look big but the major disadvantage of this engine was the power loss. This engine generates near 19 horse power at the Crank but at the sprocket it gives lesser than 13 horse power because of the loss of power at crank to clutch and gearbox. However, if i talk about the advantages of this engine over UCE(Unit Construction Engine) are not as few as disadvantages. As

 

1- The vibration In this is very less compare to use.

 

2- Ride stability is also somewhere better due to less vibrating machine.

 

3- The Thump, because of heavier crank and steel engine and this is the point which every one know about bullet the voice or noise or sound whatever you want to say you can say it because different people having different opinion for that but the thing which is common in everyone's is that the bullet is a MAN thing it is tough heavy and muscle. specially the older once The C.I bullets.

 

4- One of the most discuss able point is the gear on the older cast iron engines was on the right side with a neutral finder lever so no matter in which gear you are just one press to that lever and you will be in neutral just like that, the brakes on  the left made it a quite difficult to ride for new bullet riders but once you got familiar with that you enjoy your ride in all conditions. Back then this is the point due to this people say the bullets is not for everyone and only for The Man.
