Yes, after running the Michelin Commander II 140/75 VR17 ( a terrific tire) I ran the Ex Max 130 (also a great tire) up front on my Mulberry (red) Mistress and, to my knowledge I was the first person to run either tire on an R3 - done voluntarily as the "crash test dummy" with the careful and considered advice of IMFASTTOO.

Both of those front tires enhance overall handling and maneuvering considerably, especially vs. the blimp-like stock 150 Metzeler. Yes indeed, the 130 makes the bike feel about 200 lbs lighter just as the 140 feels like it shaves about 150 lbs. The 140 can be safely utilized on any Rocket year/model, however the 130 is a no go for any R3 equipped with ABS, as it will cause the system to become inoperative.

My ride puts about 200 hp and 175 lbs of torque to the rear wheel and that is why I am going back to the Michelin in front. When pushed under hard acceleration the 130's tracking/traction is a wee bit too light, causing a bit too much front end dancing (just a shade too light) for my liking. The 140 stays noticeably better planted/connected and I believe, due to its Aramid belts, it can wear approx. 20% better than the B'stone 130.

For some reason, these slightly smaller sized options for the front wheel has remained a best-kept secret. Bottom line - they both provide better turn-in and tracking under normal riding conditions and they both "lighten up" the feel of our beasts under all conditions, but most noticeably during low speed maneuvering. Both will make your Rocket III more responsive (less rider input required) and make your ride handle better overall - it's almost like adding power steering, only in this case it gives the rider and much better, more precise feel for the road, while simultaneously making it ergonomically easier to "handle" the bike's mass and inertia. The improvement in ergonomics or in your bike's geometry is also best when paired with the 1/2" taller than OEM B'stone Exedra Max 240 on the rear.

Try it, Chip - you'll like it!
 
I have trouble seeing that dropping two tire sizes from the 150 down to the 130 will be an improvement in handling. I need some insight from those of you who have made this change.
A 140 front tire will makes a big difference in handling everyone thats tried one likes it
 
Indeed! I first dropped down to the 140, then tried the 130 and now, for the reason given in my last post, returning to the 140. Just do it, Chipper - you won't believe the improvement!
 
You guys have me wanting to pull the 150 with over 7,000 miles left! I seem to be way behind the curve on this topic. Thanks again.
 
For 200 bucks (installed) you will definitely appreciate your 2017 riding season waaay more better!:cool:
 
Yes, motolink, other than the OEM rear tire size (it being a 245), that is correct.;):cool:
 
Ditto to Phil's comments, I took the 140 path and are currently using the130. Wouldn't go back to the150.

Chip,
In simple terms - Reducing the rolling radius on the front brings more weight forward and reduces the trail.
Because the front tire is what turns your bike (via counter-steer) the extra weight adds force and traction, allowing for higher cornering speed control.
The reduced trail quickens the turning response.
Remember that our bikes are set with the front axle higher off the pavement than the rear axle! A big SUCK IMO.
Raising the rear with an ExedraMax and lowering the front with a 140 works the best in my experience.
 
@Chip the 130 makes the bike feel 200 lbs lighter doing slower speed maneuvering and minimal circumference difference.plus great milage.Check numbers at Tacoma tire calculator.

A front wheel radius difference of .63" is a lot in terms of handling response.
Couple that with a rear wheel difference of .48" (ExedraMax) and you have a tremendous change!
Me thinks the 130 front is too much for a Roadster as it creates clearance issues with the peg rails.
Trust me, I know this! :D
