Posted: 22:35 - 02 Sep 2018 Post subject: Dealing with tar repair lines/tar snakes/seams in the road? |
|
|
Hey all, I've got a a few questions about the proper way to deal with tar repair lines or seams in the road.
1. I've ridden a few 125s over the past few weeks (CBF125, CB125F, YBR125, SR125) and they've all felt similarly skittish going over these lines at 40-60 mph, as if the back end wants to misbehave. I did some training on a 650 and it felt completely normal and planted over the same lines. Would better tyres make a 125 feel more stable over these lines or is it the lighter weight and smaller contact patch that makes them skittish compared to the 650?
2. Sometimes there's one repair line or what looks like a concave 'seam' in the tarmac in the middle of a lane continuing on for quite a long distance. What's the ideal lane positioning if you want to avoid it? E.g. if you're on a dual carriageway or motorway do you ride to the left or the right of it or does it depend on if you're in the left/middle/right lane?
3. What are "tar snakes" called over here? Seems like it's mostly an American term.
Thanks!

It's called over-banding.
No, tyres wont make much if any difference; all you may do is shift the compromise overall, and probably not for the better.
They are a pain on big-bikes too; any riding banding better isn't down to the tyres, but the weight that's what 'should' beg them tyres.
Actually... if anything, narrower tyres would probably help... do push-bikes have such issues?
How to handle them?
Keep off! Banding tends to be tar, that isn't gritted like tar-mac, they lack grip and can be notoriouse in the wet.
When you have to cross them? try and cross as 'square' to them as you can; make a deliberate turn accross them, if you need to, make the path accross the band as short as you can, rather than pelonging how long you are riding down the track, tyre robbed of grip and trying to fall off the camber.
But most important RELAX... keep your eyes open, watch where you going, dont pussy foot, hoping they will go away or wondering how best to tackle them, just do it... and keep loose grip on bars and LET the bike do its thing, dont fight every little twitch or reacting to ever little change, just go with the flow and let the bike sort itself out... it will probably do so with a LOT less drama than if you try and do 'something', which is more likely to make matters worse. ____________________ My Webby'Tef's-tQ, loads of stuff about my bikes, my Land-Rovers, and the stuff I do with them!

The way to avoid them is not to look at them.
Honestly, and it's harder than you think. The human brain makes you steer towards the thing you are looking at so look at the several feet of clean road you want to ride on, not the couple of inches you don't. .
I found visualising a line in front of the bike I want to ride along can help with training to do this. ____________________ “Rule one: Always stick around for one more drink. That's when things happen. That's when you find out everything you want to know.”

As a fellow newbie, I don't mind telling you that my heart dropped into my stomach watching that too. The fact that there was seemingly nothing threatening, and yet it took him down so suddenly. And it doesn't help that I've already come off my bike from a stupid mistake, and I'm still trying to get myself back on track.
Still! I do see one potential redemption. I watched that gif several times, trying to find a cause, and it does seem like he just happened to accelerate right at the moment he hit that tar streak. Might be just more than the tyre could handle.
I'll admit, it's still pretty scary that something as stupid as a wee line of tar can bring a bike down, especially at around 50mph. But it does help to know that there was still an element of rider control at play, so it's probably not something that could "just happen" any time.
For instance, I saw a comment from someone who said they always switch lane before they hit the throttle, which is something I intend to keep in mind. ____________________ Complete newbie. Full of fear. |

Yeah it's difficult to imagine the actual circumstances as the GIF is sped up and there's no sound but you're probably right, these things can be mitigated like yo say even by something as simple as making sure your lane change is complete before accelerating. Sounds like this guy was an experienced rider though. Having said that I've gone for a few wobbles on my little 125 even just crossing the painted white lines in the wet so just goes to show how easily it's done. He's lucky there wasn't any oncoming traffic when it happened... ____________________ Must Go Faster

I did something like that on an MZ once, and ended up in a hedge on the wrong side of the road. |
