19" wheel conversion for C5
« on: June 28, 2010, 03:55:23 PM »
   Hi Guy's, been away for a while, been busy with my other life of Cafe racers and other classics. But I have been checking in, and there as been some real good topics.
   My question is, has anyone tried the 19" wheel conversion on the C5? I noticed their selling it in the new catalogue. If so, has it improved the High speed handling/stability? What was involved in the conversion? New fender or just longer fender stays? What tire did you use? How's it look? etc, etc,.
 Thanks, any info would be great.
  Dan.

Done it .... It pretty much just plops right in there - ALTHOUGH the fender stay bolt holes MAY need to be slotted for good clearance. It adds a degree of rake or two to the bike - it does enhance the stability through this and its larger diameter (gyroscopic effect). Sadly - the bike was not able to be "muled" as much as I'd like one to be before it got snatched up for a "trailer queen", so I can't tell you any more than that about it. Right off the get-go, however, it was fantastic! It fills the front mudguard ALL the way and looks rather custom, BTW ....

 Cool, thanks Scooterbob. What tire did you go with?  Avon road rider's, to match the rear?

I just did the front wheel - and I kept the Avon SM that was mounted on the wheel on it. As I said - I didn't have the proper time to see the project ALL the way through - but the difference was absolutely astounding. BTW - The IDM bikes have the 19" baloney on the front .... they get ALL the cool stuff!! Hahaha!   ::)

I'll give it an educated guess:  IDM = Indian Domestic Market?
There's something that doesn't make sense... let's go and poke it with a stick.

  Sounds good, I can go with that.  Now how about Avon "SM"?

Lets just stick with SpeedMaster on that one. Don't let your mind wander.

The C5 I got last year was my first motorcycle so I don’t have much of a comparison base.  What is unstable with the 18” stock front wheel?  When you say the 19” is more stable, what does that equate to?  Does it corner better or handle better at higher speeds?

There was no mention of instability in my earlier post - I said that the bigger wheel/tire ENHANCES the stability as it has more (naturally) gyroscopic procession and alters the rake by picking the bike up an inch or so in the front. What this amounts to is less "wobbles" at speed when in the wake turbulence of a truck - or in a stiff crosswind on the road. Your bike is just fine - it is one of the best handling bikes on the Planet today - remember that the handling and suspension engineering was done in Italy - and those boys know what a good handling bike is ALL about. I dare say that the new C5 in stock form rivals the Ducati Monster for quick turn in and the ability to drag the foot pegs about off of it ..... fortunately, there are a couple extra where I ..... er, ah .... I HEARD that you could do that ......  ::)
