I've done all the brake upgrades and its really down to what your wanting. Bypassing the ABS will make the biggest change to feel, next is replacing the MC, and finally the calipers. If your wanting an increase in power, I'd go with pads and cast iron rotors as the biggest improvement. As far as lever consistency with heat buildup, go with stainless or Ti caliper pistons.
 
Gotta also take into consideration that the system is freshly bled right after the pump is deleted. My buddy still has abs pump plumbed and after doing corsa carta (sp) master the feel is amazing

That fuel cap pisses me off. Just got what I thought was the coolest one available. Not

Their rear sets for my old 99 are SICK too
 
It'd be fun to calculate pound savings per $ somehow.
I find it odd and hilarious when I hear MotoGP pilots gushing about their weight and how they over ate last week with skeletal faces saddling their 250hp bikes.
Ya, at a certain point it's better to skip the donuts than shaving grams off the bike.

There is also the laws of diminishing returns at work at all times in motorcycle racing. The faster you go the more expensive it becomes to acquire more and more marginal gains

a $28k V4S can get within 2 seconds of a $350k WSBK bike which will get within 2 seconds of a $1.5 million Moto GP bike
 
Highly doubt a blue printed drive train ceramic bearings etc robs anywheres near 75 hp

That’s almost 25%

Maybe if you are are trying to spin it 20k rpm?
 
he was talking about GP bikes, which make in the neighborhood of 300-330hp
then I said the the HSBK V4RS makes 255hp at the wheel
 
Oh gotcha

I am getting old...

Almost impossible to imagine naturally aspirated 1000cc engine making 330 hp

Damn
 
Didn't Suzuki let their MotoGP bike run a lap or two of the Isle of Man course and even though the rider was taking it easy and didn't know the course well, it was fast enough to be in the top 20 lap times of that year? Pretty sure it happened in either the late 2000s or early 2010s.

They're so far out of the league of normal motorcycles I doubt barely anything from riding "streetbikes" helps in building skills for GP.
 
Top 20 lap

Without knowing the layout (30+ miles) well?

And didn’t get kilt trying?

Highly suspicious

No matter what he was riding

Imagine trying to keep up with someone like guy martin not being certain of what lays ahead!

Blows my mind, when you can reach 300kph on the dash (maybe 280 considering the speedos are quite generous) and how fast that already is on a stock machine out the door. Then see Dovi hitting 357 on the Mugello straight. Mental.
I can’t imagine what it’s like going 80km quicker at that point.

Agreed - when I watch racing, I’m constantly struck by how differently the prototypes seem to move and react compared to production based bikes.

My bad, it was Cameron Donald riding the Suzuki GP bike in 2010. So, rider knew the course well. Took it easy on the GP bike and still landed in the top 20 lap times that season. In the video he says it was actually really easy to ride, but maybe that's a byproduct of being used to riding machines that are always on the verge of complete loss of control.

That makes sense to me. Motogp bikes are worth hundreds of thousands or maybe even millions? The factory Motogp team likely told him that he better not crash under any circumstances.
 
If you crash at the TT you don’t slide out into some gravel

Would prolly wanna be real familiar with BOTH layout and machine

And WSBK lap times are often comparable to motogp even though they spend way less money spinnin em

: )
 
That was Karl's point. Diminishing returns. Gotta spend tons of money just for another second or two of lap time. To be fair, when they compare WSBK to MotoGP, they often compare WSBK laptimes on qualifier tires to GP race lap times. WSBK guys aren't usually going that fast in a race since they aren't on wildly sticky qualifiers (or are trying to preserve the tire if they are running SCXes). Makes it seem like the bikes are closer in capability than they really are.
