And yes - it was proper tankslapping - not just wobbling. My shoulders and forearms are killing me from the bars violently moving about. I'm just really glad someone was on my side on Saturday or else might not be here to ask what i've done wrong.

Feel more than nervous now though (i'm still recovering from a broken back from snowboarding last year - hence the back protector in the pic - cheers for that unflattering pic by the way dave!!)

Anyway -really appreciate your views/tips/advice/comments etc! Big help. Ta muchly. Helen

The worst slapper I ever had, the front wheel didn't leave the ground at all, and I was going in a straight line... Didn't hit a convenient object either. Just got unweighted enough to get out of shape, and the rapid weighting and unweighting served to set things a wobbling.

My point is that there's no one reason it happens- but hard acceleration's probably most common exiting corners, in road use, so naturally a lot will happen on the way out of a bend.

I've only had one proper slapper and that was on a Honda Bros of all things. What I do know was main contributing factor was me mucking around with the suspension.

I'd put in a shock from a different bike and set the chain tension incorrectly. Yours truly did not take into account/forgot the shock had a lot more stroke. Hit a dip in the road and bike went mental

went on a long days riding with my local county riders group..

One of the ladies. helen , who rides an 03 R6 and rides it very very well had a major tank slapper on the M6 at about 80mph.. ! and it really shook her up..

didnt witness it as I was in front of her.. which is rare!.
we were last 2 in a group of seven

just noticed she wasnt behind me.. so slowed down and she was tootling (50ish) along.. I thought something mechanical.. so when we all pulled off and stopped at lights she said she thought she was going to die and was clearly upset..


into a lay by and a sit down for her and she was Ok to proceed after 10 mins.. to a hot coffee stop

but- she is worried it was her riding or something to do with her bike>??

so what causes tank slappers.. ? too quick lane change?
hitting a cats eye at 80?..

mefinks it will afect her confidence in herself and her bike and want to reassure her that it aint her fault.. I have never had one.. NEARLY did over that hump on the way to Hawes(norf meets south 06) so I kinda understand the feeling

but no lie- she was white as a ghost. .. !..

and- she is a super rider.. its not a woman thing I assure you.tyre pressures were fine etc etc..

uneven wear on the front tyre?

loose head bearings?

low pressure in front tyre?

id advice getting a damper big time....i had similar situations...one by uneven wear on tyre and once landing a wheelie on a cat eye!

dampers been fitted and simmilar situ came up trumps for the damper.

it will help her confidence if she has one fitted

and i hope its not put her off.
