MotoGP riders are pushing to make the championship's tracks follow Formula One's lead and replace gravel traps with asphalt run-off areas, autosport.com can reveal.

Kenny Roberts Jr., a member of the rider's safety commission, believes that flat asphalt areas are much safer if riders come off at high speeds, and claims several of his colleagues feel the same.

And they want circuits to consider making changes in areas that they feel gravel traps are unsuitable.

"On some corners we want gravel, like the slower ones, but on the faster corners we want tarmac," Roberts told autosport.com.

"The run-off at the first corner of the Phillip Island track has grass as its run-off, but we must make sure that there are no ruts in the grass to kick us up in any way. That's what really hurt me when I fell off the Suzuki in 2005.

"They are going to make some improvements there, moving the sand/gravel trap that beat Loris (Capirossi) and I up two years ago and move that further towards turn two. They say they can do it."

Just like new F1 tracks have incorporated more and more asphalt areas, so Roberts thinks that MotoGP venues must now follow suit.

"The future of race track design is going to incorporate a lot more tarmac because off-line the tarmac gets dusty. So when you push the front in third gear, you end up in the gravel trap. If you just slide on tarmac that's better, so long as the leathers hold up..."

so what do u think , more asphalt areas or gravel ?
 
I'm hardly going to argue with KRJ over what's best. Thank god I've never come off the bike at high speeds and I wouldn't like to try. I guess gravel probably slows you down faster than a 'smooth' slide across asphalt. So it's probably more a question of whether there will be enough space for them to slow down before hitting the boards.

well i have & i would rather there have been kitty litter than asphalt. .... pillows would have been best of all! but racing is different & i'm certainly not going to dispute the experts.

exactly what i was thinking. i wonder if theres something inbetween they could use that would slow them down enough whether there still on the bike or sliding on there arses but not flip them up in the air like we see on uneven surfaces such as grass and gravel.
 
Great article. It nice to get insight like that but kinda scary when it makes you think about the tracks we have around here. Any around here been to shannonville?
 
Kenny's fallen off a time or two, I'll take his word for it. I just wonder if they've factored in how long it could take them to come to a hault and whether today's 1.4 mm kangaroo leather can hold up to extended slides.
 
^^^Kargaroos are tough .......s apparently

I'd better buy stock in "Airfence"!!!

on the serious side i think JR knows what he is taking about. he is the pro and having crashed a few times he sure knows whats best.
 
I have my doubts, because a lot of the times when bikes & riders go straight forward out of turns for the slightest mistake or get pushed a bit but do not fall, mostly they ride through the grave still on the bike but at high speed. Gravel that, even slowing them down strongly and with great run off areas, they reach the fence and fall, but thanks to the gravel it’s not that dangerous. There has been a lot of these examples, more than I can count (remember Bayllistics’ walk through the fields in Phillip Island or Kato’s accident?). So I could imagine that if it was tarmac instead, they would just fly through it coming out at over 250 Ks, with a little or none control, reaching the end of which ever distance of tarmac they put in, all the way to hitting fences very strongly.

PD. They should get gravel runoff areas Losail, gravel mates, I would put in more gravel!

I think what he means is that going off course at high speed into gravel, you're off the bike at high speed. Whereas if your tyres lock up at high speed on track, you have asphalt to brake on, and you can stay upright.
