when my 01 400ex was stock and i was in sand my gps saind i was doing 70 as a top speed, also my buddy was right next to me on his machine also with a gps and we had the almost the same top speeds off by 1point sumthing miles an hour. no trees in the way either so reading has to be pretty accurate.

 

the problem with this is a raptor is so starved for air that you will never get it to 8500 rpm with a stock pipe its hard to hit the rev limiter in 2nd gear let alone 5th. the raptors rev limit is 8500 rpm but if you look at a stock dyno run for it its only putting out around 11hp at that rpm were if you put a ct pipe on it its producing 44hp at 8500rpm remember a pipe dosent change a bikes top speed,just how fast it gets there

 

i dont think a 450r will do 90 with just a hrc kit, and a pipe.no way

I dont think so either, unless there are gearing changes you cannot go any faster than your gears can take you, dosent matter if you have a 100HP
