No bike before long. Put the air filter back in!!! Your destroying your bike. Any performance gain is not worth it.

20,000 km so far no problems....35,000 km on my old bike and they are both going strong.
If you want to make your bikes not last as long as they should then sure keep the air filter off.

But it will ruin your bike in the long run.

Also, 20,000 km isn't sh!t. So it may not show signs of damage now but it will when dirt gets into the wrong place.

Best I've seen the CBR250RA pull was 171 Kph (106.25 mph) carrying ~95 Kg (210 lb) down a steep hill.

Edit: That was a stock bike, rider tucked in, doing around 9.5Krpm in top gear.

What's the opinion on K&N filters? - K&N Air Filter HA-2511
Got a beowulf Exhaust fitted, lost a bit of speed, was wondering the Air filter would be a worthwhile purchase?
Opinions?!

Don't. Actually do if you like reduced performance and lots of dirt in your engine.

Opinions are divided on this one. Initially I never thought I'd use one but at approx 15k km's I decided to try it out. Time will tell if my engine fouls but 3k km's with it installed and the bike is running better than ever.

A long as I'm on a normal sitting position I can drive between 138 kmh (85 mph) and 142 kmh (88 mph). I think it varies because the Autobahn is not always 100% flat.

When ducking under the wind shield and going downhill the highest speed was 160 kmh (99mph).

All those numbers were from the odometer, so it's basically minus 10% to get the real GPS speed.

I would say those numbers are right on factoring in the odometer error.

I also made a measurement with two GPS devices recently and 150 km/h (93 mph) displayed on the oddometer were 138 km/h (87 mph) real speed.
