I’m looking for information about how front wheel size affects motorcycle handling.
I can tell there is a difference between the V7 and the R1100S in the way they behave.
( Yes, the geometry of the bikes is quite different, but they have more in Common with each other than with the XR ;) )
Tried googling front wheel size, but mostly got Stuff about big 21“ wheels like the Honda has…
I understand a bit about rake and trail, and what it affects.
any one have a pointer to an article or Site.

thanks.

I’ve written about this many times.

You are the perfect candidate for Gaetano Cocco’s book as well as Vittore Cossalter’s book too!

Buy. Read. Learn!

There is absolutely nothing about how the physics and interactive relationships of how and why a motorcycle does what it does, that these men do not explain in complete detail.

They are both masterpiece of information.

Here is a very good used paperback for less than $9 !!!

As I said, the other definitive book, of whom Cocco references in his book, is Motorcycle Dynamics by Vittore Cossalter.

Indeed, I purchased Motorcycle Design and Technology when Scott referenced it several months ago and can now vouch that it's an excellent source of technical information regarding motorcycle design and handling.

If you all didn't live so damn far up North, it wouldn't cost so much to get crap to you! :rofl: :rofl: :rofl:

Damn Aussies, same thing, just the other direction.... :rofl: :rofl: :rofl:
 
So I ordered the book off an EBay seller not realizing it WAS WorldofBookUSA :D
Not the WOB UK whose site I ended up at initially with a 19$ delivery.

Scheduled to arrive May 30th or sometime in June ... Arrived today, time to get Learning 👓

So, I’ve started reading my book, it is really quite interesting and very technical…( Lots of formulas )

Anyway, when I first started riding the MG after having ridden the Honda for a few year, is was amazed at how the Guzzi would almost steer itself around corners…

Now, having read a bit, I can appreciate how the smaller diameter front wheel on the Guzzi and differences in rake and trail contribute to those differences in “Feel” between it and the Honda !

I don’t “See” as big a difference between the MG and the BMW, but there are significant differences.
Perhaps not as big between the Beemer and Guzzi and the Honda, but different none the less…
