Hi

I would really love to know more about my bike, and I have been trying to for some time, but i have not been very successful

I dont even know where to start.

I dont want to know about mods and stuff, what I would like to know is what goes into making one bike better than the next. What aspects make a difference to cornering and braking, how does changing the angle of the fork by 1 degree affect the bike's performance... and everything else that I can...

I know all this would probably be part of an automobile engg course, but i dont have the time to join one of those

If someone could help me out, or show me the ropes (I am in Pune, free on weekends), it would be great!!

Assume that i know nothing, except to ride decently. (By that i mean that i dont race on crowded roads, and my only accident has been because of someone else's mistake )

If such a thread already exists, my apologies, and please redirect me

Any help would be appreciated!

Topic Approved

Quite a vast subject. But approved nonetheless. Can be useful and interesting in the scope of the forum.

Ok, Let's start ... I don't know exact meaning of what you said but let's try ...

Wheelbase: Longer results in better high speed stability, but longer turning radius.
Shorter results in short turning radius, ideal for city, but bike seems unstable high at speeds.
For a good sportsbike, the wheelbase should be short ... but swingarm should be long!

Is this an example of what you want??

insanebiker

I fail to see any logic here. The length of the swingarm decides the wheelbase largely.

What is a swingarm??

Kidding

Yes, this is exactly the kind of information that I am looking for, but also, the "WHY"s... like insanebiker said... what is the logic behind the correlation of the length of the swingarm --> "good sports bike"??

Sportsbikes --> shorter wheel base --> doesnt that mean less stability at higher speeds??

I know the scope of this will be vast, but if we could get some experienced members to contribute, it could be a wealth of knowledge!

Swingarm is a smaller component. It starts from the point it is attached to chassis via a circular joint, which allows for movement up & down (due to suspension).. and It ends nearly where the rear wheel is attached.

Wheelbase is only a measure of distance between the tyre "ground contact" points... It is even affected by Rake & Trial Setup, engine block, etc... Of course, Swingarm is an "affecting factor" among other factors.


PS: I read this statement in Bike India's issues, can't remember which one? But, it was a Bike UK Article... I "think", the larger wheelbase does add stability, simply because it allows more rear wheel wobbling (don't know the ideal word), without disturbing the chassis due to its length... Isn't it?

Joel

What are you saying man?
Why would one favour a wobble to aid stability? Your logic of an SBK having a short wheelbase for stability but with a shorter swingarm is another stunner of a logic to me. Atleast for once read wht you have typed, apart from the usual google.com gyaan you tend to collect and interpret in your own words. The disaster begins there!

Larger wheelbase adds stability in high speed. It doesn't achieve this via rear wheel wobbling as you said though. A longer wheelbase will make the tail of your vehicle more stable in high speed situations.

Swingarm of the bike will, generally, effect the handling of the bike under acceleration, braking, cornering.

There are so many permuations and combinations possible depending on what you are looking for in a bike, so it is very difficult to say what is ideal. eg:- A drag bike would not want its front end to lift, so they would have an extended swingarm.

Its all messed up guys please can you all explain it from begining some one is saying a longweelbase ????? and someone is saying small one ???

Very useful thread.

But i think..Instead of proving anyone wrong,everyone should try to correct the gyaan,provide some inputs for the stuff which somebody has wrongly interpreted in here.

So the best thing will be to provide the correct information about the basic terms of the bikes,with little bit debate..and a detailed conclusion in the end.

I have one question.

How does an Exhaust adds in the performance.with the various varaints in the Exhaust technology,Exhaust size etc.How does it works.
Also is it like a type of exhaust should belong to a type of bike(superbike,dirt bike..this classification)

Guys please provide your inputs,your expirience.I have already googled all this stuff.
Peace
