So having dropeed off my new set of Pirelli Sport Demons at the the tyre fitters I returned on my Le Mans to have them fitted.I was following a van at about 40mph and decided to overtake it, so went up to about 50mph and cruised past. To do so I had to overtake on the wide painted lines that keep the two lanes separate. They were quite thick and the front end started bouncing, very quickly I went into a full lock tank slapper, with the front tyre skidding over the white lines. I thought, this is it: down I go. By some miracle (no skill involved, even though I have done lots of off road) I held it. With my heart in my mouth I conitinued my journey and got my new tyres on.Thinking about this (which happened yesterday) I think that it was a combination of the speed I was doing and the thickness of the paint on the road surface -I reckon if I was going 5 mph faster I would have gone across them rather than bounced across them if that makes sense.I am now thinking about getting a steering damper fitted, even though nothing has like this has happened before.What’s the consenus on this -also any recommendations on steering dampers suitable?
You were riding on worn out tyres which will certainly have an effect.
The tyres were actually pretty new, but very old. They were fitted when I finished the bike last year ‘new’, but were manufactured in the 90’s!The front was over sized at 110 and I have gone back to the original 100 size…
steering damper makes a massive difference to the steering stability, eps on a troublesome bike with 16" like mine…but i have found to my cost that you wind it up enough to work well on the main roads and lanes then you cannot turn out of a junction as the steering is too hard :-(appart from that im very happy with the differnce one has made to my bike
on my ntx/xpa i had some real fun untill i fitted a steering damper ,its just so much more stable .Next on the list is a damper for the T5 im really riding it now and when over on the limit it sometimes feels like a tank slapper is just waiting to happen and for peace of mind i need to fit one .I go cheap but if i had more money and was not so tight i would go for a good one .
very true ,only ever once had a real tank slapper and that was when my norton rear wheel collapsed
Yes Baldini, this was most definately a proper tank slapper -full lock, side to side, it felt like a bucking bronco. I have done a lot of off roading and not at all bothered by a bit of head shake. This was my first (and I sincerely hope, only) full blown slapper.As I said it was by pure chance that I held on. I backed off the throttle a bit (too busy trying to hang on) and it stopped. I think it was a combination of the 110 tyre (an old Metzeler, which could well have been a rear), and the speed I was travelling at over the painted tramlines, was perfect for getting the front bouncing then into a full blown tank-slapper.I have to say it scared the bl**dy life out of me!The Pirelli Sport Demons. Well what can I say? Only done about 80 miles on them but boy, they are a world of difference. The turn-in is so quick and they appear to have worlds more grip than the old Metzelers I had on. Not properly scrubbed in yet, but so far really, very impressed indeed. You feel you can really push them and then some…Will let you know in a month or two how they progress…
Two people have told me now (if you’re reading this and one of them was you I apologise for not remembering your name)
Tyres over x (where I think x is 5 years??) are automatically considered dangerous by insurance companies and can invalidate your insurance should you need to claim.
As the Daytona has its original tyres with less than 3000kms on them, I am loathed to change them… but maybe I should?
Take 'em off and store them if you think the originality will bring a price premium at some point.
Glad you held on, and that it’s a tale to tell & not for us to mourn you over.
Ride easy, Dan.
