• There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

Front end shudder

I have a 2015 F3SE with 13,000 miles. On our last trip when I applied the brake from a "healthy" deacceleration at 60 mph the front tires shudder and shake. Is this a sign of warped rotors or should I be looking elsewhere for the problem. Any suggestions are greatly appreciated.

Warped rotor or tire ply separation would be most likely---do you brake hard on occasion ??
 
Braking

Not standing on the brakes. Traveling at 55/45 mph and stoping the bike with "reasonable" brake pressure. As the bike slows and the braking pressure is lessened, the shuddering cesses and the bike come to a stop.
I have taken the F3SE to Mike's Powersports here in Reno NV. I had the shop manager test ride the bike for an extended period of time, at various speeds, and on different road surfaces and he stated "this is a weird problem".
Again this is not an issue of standing on the brakes. Over 3000 miles the problem got progressively worse, the bike showed no abnormal handling characteristics, and with my limited evaluation following all your suggestions I did not detect a warped rotor or faulty bushings. There is no brake pedal,surging. Front tires are Hankook Ventus 4 and they have approx 4000 miles on them.
So, I have just turned the bike over (under warntee) to the shop where I purchased the it.
I will continue to keep all,informed when I learn more.
Thanks to all for your input
 
Warped Rotorsshowed both rotors were warped.

Just heard back from the shop manager and he told me that I have warped rotors. The application of a micrometer showed that both rotors were warped.
called Bajaron and ordered new pads and rotors and he has always been speedy with delivery so I should have the bike up and running soon.
Will post if there are any residual issues.

Curious

Some of the hankook tires are dirrectonal...did they install the correctly...?? We are seeing bushing problems worth checking..:thumbup:


Thanks for all the responses.
i replaced the Kendra's in March with Hankook Ventus 4 and they have about 4300 miles on them. I suppose that I could have a faulty tire, but when I inspect them they look ok to me.
 
I noticed when I hard brake the steering feels loose causing me to counter the way the force of deceleration is pulling it. (it fishtails)
I need to go to an open safe area at say 65MPH and slam on the brakes and see what happens.
I think doing a real time "test" is the perfect way to see what my bike (or yours) is capable of and if there is a problem.

Il guess its your rotors that are warpt. I am now on my 3rd pair of front rotors and the ones on the bike is on its way to warpheaven too.
From what ive heard there might be a fault in the hub were the wheelbearing is seated ? And if the hubb/bearing warps, it probably will case the rotors to fail in time.

Rotors

As promised I am reporting on the results. I had the rotors changed and the front end shuddering with firm stopping has ceased. All bushings were checked and there were no defects.
I ordered EBC rotors and pads from Bajaron and I can attest that the brakes simply work better.
While at it, I changed the brake fluid and found that the fluid (oil) upon visual inspection did NOT appear that dirty. I have 13,000 mi on my 2015.
So all is well.

If brake fluid looks dirty.......you have waited way, WAY too long to change it.

It usually deteriorates due to moisture absorption.
