Just wondering if anyone has this issue.
Was on way back from work went round a roundabout. I leant right bike wanted to go left. The engine appeared to be working harder than usual. Was strange so held back on slip road then wen I opened it up in a straight line the engine made a funny noise (as in working harder than normal) next thing it was like someone pulling the front wheel from under me it all seemed to seize up. Then the rest was in gods hands off bike head first down the motorway I was like a tumble weed.
Fortunately my gear took 90% of impact but snapped finger plus deep cut to hand. Lucky escape in my eyes. Anyone else heard of such a failure.
Mine was an 05 valves done in march apparently. Noticed there an 08 sduke post with similar issue.

Feck, not heard of many SD's going when was oil last changed?

Know Tripod Dave's rings were knackered so good job he had heads out when he did, but not really heard of many others.

March this yr. I hope my insurance can diagnose an accurate fault and look forward to the result. I'm just glad I did the sensible thing and waited till no cars around an I was in a straight line before I tried to work out. Not that I could have stopped anyway it happens too damn quick

That all sounds very odd. The engine has definitely seized? Why would it pull the bike to the left when you tried to steer right? And the rear locking would surely make the back end slide one way or the other rather than the front end tuck. Did you grab the front brake when it started going wrong?

Anyway glad to hear all your gear did its job and you are ok. Hope insurance sorts you out a new bike.

I didn't get chance to brake it has baffles me. I checked the front tyre and it seemed fine. The only thing I can think of is if the engine was failing on the corner it would slow me down and move me towards upright and like a sense of pulling. I can't explain the other part though as I never cover my front brake unless approaching a hazard. I really need to know though unless something has come off and trapped my front wheel. I'm just guessing but not fit enough to travel to visit it myself to inspect.

I can't confirm the seizure but that's how it felt and sounded.

Would a front wheel baring going cause that affect

After thinking about this I had something similar as did Colenel Klink put the wrong fluid in my bikes front brake system and one side of the caliper pulled on giving the diagnosis of veering.

I think your brake claiper may have seized.

Not changed the brake fluid have you?

For me it was all fine, I was having some fun with a R6 and suddenly the bike stated slowing. First thing I thought was engine seizing as it sounded ok but something was pulling the bike back. I went to change down and as soon as I touched the clutch I realised it was the front brake. Managed to get her safely stopped and the left calliper was fooking hot and the disk a bit blue. It took about 5 mins before the wheel would turn again. Once it had cooled right down I limped the 30 miles home. Salt and shite from winter had caused the pads to not retract properly and when riding hard the heat had made it 10x worse. I got Brackens to sort it as I was a bike mechanics noob then

if you were going around a roundabout and the caliper or calipers started to seize if would give the feeling of veering because the bike may have been trying to stand up.

Sorry to hear about the crash!
Some speculation about the possibility of one caliper causing a swerve...
I too have had a lot of bikes, and some with only one single front disk that never pulled when braking; however, maybe these transmit forces to the fork differently? I know that about 25 years ago, I tried to drive my FJ1200 away from a bar without taking a padlock off one of the front disks

Ok...one more time. It is physically impossible.

No weight to offset caliper on one side or anything similar is used in the design of single rotor equipped bikes. The braking load gets transfered from the fork leg through the caliper to the rotor, wheel hub, spokes and then contact patch on the tyre. There is no twisting, counter weighting or other black magic going on here. This is simple engineering.

I used the 'several bikes over the last 35 years' comment as an example...not a slap in the face or I know more than you because I've ridden more than you.

Just trying to explain that the aformentioned comment is not possible.

See your point Lowrence about the physics etc, but when my brakes seized it pulled the bike to the right I had to stomp my foot down quite far forward to stop the bike from falling over, it was by some traffic lights and I distinctly remember it.

Hopefully Timboo can provide some answers when he sees his bike?? any update?

Talk about a long drawn out process. I've not instructed an inspection as of yet as I have made contact with a solicitor. They deal with all forms of road accidents and have a sound knowledge.
I didn't want to instruct an inspection off my own back as the person/company may not have the correct training/qualifications to present any findings in document form or If need be a court.

The whole process is a mare at present.

The solicitor is just waiting to get authorisation from my work to pay for the inspection.
I'm trying to keep everything with 1 company so less space for error in my eyes.
I reckon I'll be still here 2 yrs later settling this one
