i remember a cycle world article years ago where a zx-12r didn't have the speed limiter installed yet and it went honest to god, just over 200 mph.

i also remember an article (forget which mag) from not too long ago where they tested the top speed with and without the limiter on a zx-14. with limiter it reached 184, without, only 188...

which brings me to my question. why is it that a bike that is lighter, more powerful, and more aerodynamic SLOWER than it's predecessor?

am i missing something?? please, someone explain

I dont remember any test of the 12R going 200 mph and especially OVER 200 mph. The ZX14 is heavier, maybe 10-12 hp stronger than the 12R. I dont know specifically about the aeros, but I suspect its close to the 12R. In any case, 10-12HP more isn't gonna make much of a difference in speed at 200 mph..

I didn't say it didn't happen, but I have owned a ZX12R for 7 years and dont remember any test where it broke 200 mph bone stock. Its pretty well known, that its top speed is in the 180's to 190's, not 200 mph or over. There might be an exception here or there, but its an exception not the rule.

Well stock a zx14 is not going over the 186 limiter ..But at Maxton a zx14 with 24 miles in the clock went 196.1 breaking the stock production record....Some say it wasn't stock because they swapped the 17 tooth front sprocket for a 18 tooth ..This gear change fools the limiter so you can go faster than the 186.. This gear change while not stock is ok by Maxton rules for production class...Brocks own zx14 broke 200 with a piped and P/C zx14, thin oil and trick wheel bearings....But the motor was untouched...No Busa or zx12 with just a pipe/ P/C has run 200... No Busa or zx12 that i know of has gone 196.1 with just a gear change ..
