Very informative !! Techno
I would like to add what I came across recently with Yamaha.

Y.R.C.S : Featured in the FZ16 Yamaha Ram air Cooling System it is nothing but a scoop which directs cool air to the spark plug area. (a big thanks to Mr. Shankar for throwing the light on the same)

Cross plane crank : The new tech in R1, with pistons just at a difference of 90 degrees at the crank compared to the conventional 180 degrees. This smoothens the inertial torque at the crank this gives better response to throttle.

Great write up; check if this can be included

there are twotypes of suspension layout i know of

1. Twin-shock / Tradidtional : you would see this almost most of our indian bikes; the not the best you can get in suspension; primarily driven by cost factor. Not meant for high speed riding needs as it flexes & cannot be strengthed as extra material is extra cost; the downside is since most of these shocks are mounted close to rear axle then the stroke of these shocks needs to more or less the same as the stroke of the swingarm which means that it has to work harder & the oil can loose its suspension properties pretty fast.
exception i have seen is high end naked bikes like ;last years CBR400 super four uses a similiar set-up but has Ohlins & alumimum box section so it is amazing. then again they are Ohlins


2. Monoshock / Single shock: This one has various types the advantage over the above is that the stroke is much lesser as it is closer to the front axle of the swinagrm.

Type one is what we see in the Honda Unicorn with shock mounted on to swinagrm & top of the frame it is the most basic form of mono you can find; however not completly giving you the rigidity that you would need; quite similiar to what you find on rd350LC. Purpose weight & cost saving though not much better than the tradional type on ride quality.

The new monoshock which you see in duty in most of the biks like today are one in which the swinagrm is called a H shaped swinagrm with shock more or less perpendicular (Right angled) the top is again attached to the frame however the bottom is attached to the swinagrm with what is known as dog-bones. ride is better as these bones reduce the stroke of the shock much more than the type one monoshock & more suited for performance riding. This is very similiar to what you have on the R15. (Tip; if you want to change the ride height on the R1 make custom dog-bones shorter by whatever height you need )

lastly then there is the single sided swinagrm mono shock not much different from above just that it is a single side; do not know if it has any benefits on the ride

amazing

Thanks soooo much for the amazing effort and detail you've put in here..! I'm sure many would benefit a BIG lot from here to their tech know-how..
I, personally, really liked the "HRC" and "Desmo/Ducati" mentions there..

Great work!

Cheers,
Jas.

Nice one Technocrat. Many of the older English motorcycles used the dry sump, like most of the AMC machines, Matchless, AJS, etc.

Very good detailing about suspension.

There is one other kind of suspension also, i would like to add for completeness, called as linkage suspensions which have a linkage mechanism between the swing arm and the shock absorber (or damper). These are seen on high end BMW's and other European makes only (not even ion jap bikes)
