Hi.
This one is about sprockets. But, I'll promise, it will be an interesting one.
This intro is for the uninitiated.
We all know sprockets. Your bachpan cycle has it, and your 70 has it. They are a mechanism to trasfer power to the wheel, from the engine. Gararis! Those spiky, round discs.
Now, they are of different teeth, meaning how many spikes/protusions they have on their disc. Now, I tell you this; Changing your garari/sprocket to a different one (with different teeth), can make a difference on your bike.
But it's one of these two.
Superb Pick, but less top speed. Thora more Petrol-using (lesser Mileage).
Superb top speed, but less pick. Less petrol using.

Now, let's get to the real deal.
Through my theory, you can expect your average 70 to go to 110-120 max, ALSO 50% faster pick, and even have an option for high fuel efficency to 50 kmpl, without even touching the carb!
Cg 125 aur yb 100 ki baat bhi na karna, kaisay sher un ko banadein gain ye mod. Aur gs 150...
So, let's go into the how's.
Your motorbike has 2 sprockets, one at the back, and one at the front. The front one is smaller, and conversely, the back one is bigger.
For my theory, I will only do it on the front sprocket setup, because changing teeth on the front sprocket of the motorbike, has 3x of the more effect than changing the same number of teeth on the back sprocket of the motorbike. Also, the chain will not go too tight or loose.
It's actually really simple! Get 3-4 front sprockets. All of different teeth.
For example, I take 3 sprockets; 12t, 14t, and 17t
I will take them, and engineer them into the front sprocket area of the motorbike.
I will make a sprocket shifter, controlled by a super cheap, mini computer, (200 rupees ardurino), and give a specific kmph range for the sprocket shifter to shift the chain onto each sprocket.
And I will make the system like this:
0-60 km range: Shifter will make the chain shift onto 12t sprocket, which has lightning fast pick. But can't go beyond 60 kmph in this sprocket.
60-90 km range: After 60kmph, the shifter will make the chain shift into 14t garari, which will go with good pick, and good top speed, nothing special. Not more than 90kmph.
90-110 km range: Shifter will then make the chain transition into last and largest sprocket, which will be of very slow pick, but high top speed!
Getting me? Of course, we can go even further than that! But the limitation here is of he chain tension, which stops our khwaab of 150 kmph on 70.
And, on fuel savings! The bike can be made to have a function, which, upon request, will shift the chain to the biggest sprocket, which will be the most fuel efficent! Why? Lower RPM's for the same speed, on the bigger sprocket. Lower RPM= Lower Petrol Use.
And, yeah... Sorry to say, but this won't be possible by yourself on a regular bike, at least for now. But, for the best results, the manufacturers should step up and start incorporation this awesome feature into their bikes. Their 70's and 125's are long outdated and need refreshments, like these. If they don't, we'll figure out a way.
So, brothers! What do you think?! This has much potential. And, to tell you one thing, millions of vehicles already have these same features. But they are called gear wali cycles, not Motorbikes.
Phew! Wasn't easy writing this. But, needed to get this out.
