Default What am I doing wrong?

Hi Folks,

I seem to have some trouble with my technique on gravel roads.

I know the CBR is not a dirt bike, but we are talking about flat smooth roads here. Now for starter the gravel we get here *is* some of the slipperyest in the world has its all very rounded little marbles on hard packed dirt inter mixed with sand drifts.

But when I ride even in a straight line the front end just wants to tuck under to the point that slowing down I have almost got both feet on the ground to steady her. Other people riding the same roads with sport bikes dont seem to have the same problem.

sounds like you could use a Transalp...or Versys??


Soft pack rollers and a heavy nose probably not a good mix..

Drop your tyre pressures front and rear, down to 22 lbs It'll increase stability on slippery stuff, as your contact patch is bigger. It'll still want to tuck under if you turn too quickly, though.

I lowered front end about 1.5cm. And set rear suspension in hardest position. Handling is much more stable than before.

Ride dirt bikes for awhile, then get back on your sport bike. You wont have a problem anymore...

Well shadow in the old days, this would be considered sound advice. But nowadays, you must take into consideration, someone might be running the continental sport attack or road attack tire, which the lowest safe recommended air pressure would be 38 psi. Anything below that and the tire stands a good chance of breaking loose from the rim completely it is designed to run at 42 to 44 LBS thought I would just throw that in there

I'm just guessing here, but all things being equal if others are making it "without a problem" my guess would be it's because you're going too slow and/or not keeping a steady pace. Opposite of what one would think, you're actually decreasing stability by going slower and/or changing up your speed constantly "up to a point" .. going too fast would have the same effect so you have to find the fine line (based on the condition) that gives you the most traction .. when speeding up 'no jerky motions' should also go without saying ... in those conditions it's best to let the bike do its thing and not put too much pressure on the grips .. keep a light hold.

Thanks for that, Gunny, correct as usual.(even about the old bit) he he...
It seems to me though that the Hurricane is probably the worst road bike you can put down a dirt road, as it's nose heavy, and the all up weight is very high too. If I was running a set of Conti Road Attacks I wouldn't want to take the bike anywhere near a dirt road in the first place.
I've done some dirt on mine, nothing significant, maybe 5 miles of soft stuff each way, and some in the soft mud when there was no choice, but it's not something I enjoyed. I have however taken a GSX1100 with the old skinny tyres down 50 miles of rutted dirt, and back and dropped the pressures as stated before, no problem........but then, it's an old bike, and not as nose-heavy as a Hurri.
