My S2R800 track bike with a 14t front sprocket with some weight removed but with my fat ass on it, power commander, k and n, clipons, stock internals will only do an indicated 210kph (131mph) before I run out of horse power down the front straight (almost a mile long).  The bike will not red line in 6th gear, just not enough power.

wouldn't your top end be better with a 15T instead of a 14t?

If he's not redlining in 6th, probably not.  It sounds like his top end is drag limited, not rev limited.  There's a chance it'll give him more top speed in 5th, but whether that'll give him a higher maximum top speed depends on where 5th tops out.

Not if he ran out of power before it redlined.  If he was bouncing off the rev-limiter with a 14t, he would be able to go faster with a 15t.

Spidey is correct (based on my knowledge...or lack of).
  I do understand this is a thread about top speed, so, WHO here has been to Bonneville on there monster? I know it is not the best place to go find out top speed unless you have a thousand +HP & SS or aluminium wheels, but would be fun to hear your stories.  I broke the 140 mark (my..and all 1098s will do that in 5th gear) on a bike there & had nervous shakes for over an hour (Greatest day of my life...on a bike  [evil])

I promise to make better mistakes tomorrow.

Drag is a big factor at this speed.  I might have been able to go a bit faster with unlimited space but for all practical purposes my speed did not increase past the 210 indicated.  The guys on liter bike at the track can reach well over 300kph before braking.

Can't help, I hit 95 the other day on my S2R and nearly wet myself...

I am new to street riding and cannot imagine the wind at 135+

If I'm understanding this right then the question is.  What is the top speed of a 2V ducati if it has fairings.  Check the paul smart out or the 1000DS supersport.  Those should be your fastest models with fairings and 2V.  I'm thinking 150mph is doable with fairings.  My s2r1000 has 14T and I get between 135 and 140 indicated on the back straight at mid-oh.  My rev limiter has been bumped up to 9100 but I don't hit it.  Not sure if it would pull all the way to it with enough room.  After 135 indicated it's not accelerating too fast anymore.  Making a wicked noise though with the full arrow race exaust and open air box though.
