well his sense of humor is open to debate I guess ,, but to a more safety oriented subject ,have you read on the forum that apparently any 140 size tire in the front like the azzaro would render the ABS useless ?? I cannot see how this would be , but you are the investigator you may find why it is considered so!...or not

Patrick I heard the 140 does not mess with the ABS but switching to the 130 does. I am not sure the Azzaro is made anymore. I did get a chance to ride Speedy's Classic with it on and it felt great. Many have been switching to the Michelin 140 in the front. I may be me but the 140 Azzaro seem to fill the front fender better then the Michelin. Not sure why and or if there is some type of profile difference between the two. Anyway as it left the front fender looking weird from the smaller tire I opted back to the Avon. I do have a extra rim so I might just have to try anyway. If so I believe I will look for someone who still has a Azzaro in stock.

still why would a smaller tire render ABS useless I need someone to show me where it does that , since the ABS ring on the wheel is always facing the electric sensor regardless of the tire size I am puzzled! unless the circumference of the rear tire and front tire are to be spinning at exactly the same rpm for both ABS rings to be in sync!! that is all I can think of but in that case the exedra max being taller than the metz a 140 up front coupled to the exedra would be similar to a 130 with the metz! to make matter more interesting I bought two azzaro while they were still available 8 months ago , as you know they are rear tires and dealership generally refuse to mount them on a front wheel claiming liability concerns
life gets interesting along the path of understanding the motorcycle designers

Patrick the ABS system monitors surface feet per minute or since it is from the other side of the pond probably surface meters per minute. So the smaller say 130 tire circumference is different from the programmed parameters in the computer it messes the system up. It would also probably happen if you went with a larger style profile front tire (if possible) The two rings monitor how much they rotate in ratio. There probably is a tolerance in there also which is why you can vary slightly without throwing any errors.
Hope this helps

YOU ARE THE KISHIOGAMA
written that way it makes senses ( the tolerance would also take into account the wear of tires ) we are really a long way from say the original ABS on fokker 27/ 50 which in fact was a( KISS )foolproof system

That is simply just NOT the case!
I have run three different brand 140s up front without issue to my ABS.
The 130 does fault the ABS, but the brakes otherwise work fine.

got it and warp has given me the technical rundown

Patrick,
The OEM set up leaves the rear axle ½" lower than the front axle. NOT conducive to good handling.
The Exedra Max brings the rear axle level with the front axle. Better handling.
The 140 drops the front axle ½". Best handling.
On the Roadster, a 130 will further drop the front axle, faulting the ABS and reducing lean angle to dangerous levels in my experience. Handling, although quicker, will be dicey and things will dig into pavement if you are a twisty boy.
