The air drag is pushing harder than the motor can, at the speed where your RPM stops increasing before it gets to redline.

 

Put a fairing on the bike or change to a REALLY big motor!

 

Drag increases by the (V^2) speed squared (2x speed = 4x drag)

Horsepower required increases by the (V^3) cube of the speed (2x speed = 8x power required)

 

In the Coast Guard example below the characteristics of the air drag and water drag appear to be

changing with speed to make the ship slower than you would expect by the theoretical HP vs V^3 relationship – the

cube root of 33000/6000 is ~1.76, 1.76 x 18.5 kts =32.5 kts vs the 29 kts noted below.

 

A KLR with a speed fairing is an interesting concept!

 

QUESTION

Has anyone been faster than 95 mph on theirs and what is the fastest speed that we know has been demonstrated?

To give a real-world example that I'm familiar with: A 378-foot Coast Guard High-Endurance Cutter has a dual power plant: 2@ 12-cylinder, 24-piston main diesel engines, roughly 3,000 BHP each. and 2@ Pratt and Whitney main gas turbine engines, roughly 18,000 BHP each. On the diesels at flank speed (balls-to-the- wall), top speed is 18.5 knots (21 mph) On the turbines at flank speed, top speed is 29 knots (33mph) So, adding 33,000 hp (eleven times more power) only gets you 11.5 more knots more speed.  The effect is amplified in water, but the same effect is true in the wind.  A fluid is a fluid. -Jeff Khoury

#ygrps-yiv-1197291218 p {margin:0;}I think the turbines are governed back a bit in order to not exceed certain stress loads on the hull.  I've personally seen 31kts, but stated maximum is 29.

~~~I have to lie on the tank just to keep the front end from shaking doing an indicated 85 MPH, but I may be a fat ass and need a stiffer rear spring=:-) Never really cared to see how fast my KLR can go. I've had it up a little past an indicated 90 MPH and felt like there was some left over but the KLR in stock guise is no slab rocket...and I didn't really buy it to find top end speed Others may have better and different ideas Jake Reddick Fla.

QUESTION

Has anyone been faster than 95 mph on theirs and what is the fastest speed that we know has been demonstrated?

 

[mechanizeinc]

My green '06 always seemed to indicate accurately in my usual traffic. Trail Wings on OEM rims must be the right OD for the speedo. Riding north with the wind and a hair to my backside I passed a Yamaha crotch rocket. Glanced down to observe the tach straddling the red line and the speedo showing 107mph. I thought "no way?" After exiting the interstate I mirror checked the kid splitting a few cars to stand beside me in the right side tire groove. He yelled thru his full face "Damn!! That dirt bike'll do 107 miles per hour?!!" Now I got my ham fisted reassembly of the top end that clatters slap for 3 to 5 seconds (7 or more when it's real cold) on start up and oil consumption from blowing by them rings... with the wind to my back and a jato strapped it might get to red line and 107 again, but it's self limited to about 98mph and a few hundred revs below scarlet now.
