Rear wheel spitting up onto the fender & rear seat. Solutions?

uKER · June 21st, 2013, 10:39 AM

I'm surprised I didn't find anyone talking about this, but I just got a 300 and the worst I've found about it is that the rear fender doesn't reach back as far as the rear wheel, so there's quite a bit of wheel in which the tangent spits up gravel and water up, which ends up on the fender and the rear seat.
Rode for some miles on wet pavement during the weekend and my GF got her ass like she had sit in a puddle.

What are the options to fix this?
Some kind of "rear end hugger" perhaps?

Thanks for any help.

In pictures, it looks about as long as any bike's fender. Maybe you could bend the license plate rearward a little, or add an extension made of plastic or sheet aluminum.

Get your girlfriend her own 300

There are a few extended huggers out there (SSR's carbon hugger for example).

Bentley813 · June 22nd, 2013, 11:12 PM

I don't have that problem at all with mine.

Unfortunately that wouldn't help.
The problem happens at the rearmost edge of the wheel.

But that's the purpose of the fender... to take the crap from the road so it doesn't end up on you. And the 300 already comes with a rear-hugger, which doesn't extend super far but still at least protects the rear shock and what not. Its not perfect but I'm sure it would be much worse if you did a rear fender elimination.

uKER · June 28th, 2013, 05:52 PM

Well, I kinda agree with that, except that I expect the fender's bottom to be dirty, not the top. XD

you might need to make your own splash guard then...

Air turbulence downstream the main airflow around the bike is what makes mud and water land on places not on the tangent of the tire.

Unless you replace the original fender (no much help either), there is no much more that you can do other than making her tuck some behind you, wear a full face helmet and a back pack.

Those things will move the zone of turbulence aft some, maybe flushing some of the splash back and even improving the coefficient of drag and your top speed.

Very creative! Have the pillion wear a backpack to prevent splashes on pillion's ass... definitely worth a shot.

All that fancy talk

That is GORGEOUS.
If I saw one of those for sale that fitted the Ninja I'd buy it INSTANTLY.

The post was a very informative one.
However, that reasoning has a major flaw: there was no water in the air.
It had already stopped raining when we started riding, and no part of the bike got wet except for the rear fender and passenger seat.
Also, besides from water, I've found gravel on the fender, and I don't recall having driven through any clouds of gravel.

BTW, here's some guy experiencing the same thing on another entirely different bike, so it's not all that implausible after all.

Lol, that's not my bike, and it's pretty much from normal street riding too. Monsoons here are very wet and roads are always dirty... Not a good combination

No, no !!!

The zone of low pressure and turbulence exists behind your back and the rear of the bike any time that your bike is moving through the air at certain speed.
The air is simply trying to fill up the space that an instant earlier was occupied by your body and bike.

No rain or water or mud on the road and you don't see that happening, but there is air turbulence behind you.

Your tire is spitting water, mud and occasional pieces of gravel into that zone and then is sucked by that zone of low pressure and turbulence, landing on your back and seat.

Probably right.

These things are popular here in Asia as it is rainy season now.

I dont like the look & dont use the ninja in the rain if I can help it so dont have one.

They run about $60
