Anyone know how they build Zemke and Duhammel's Formula Extreme 600rr's up to 130-something hp? Just curious....

pistons, cams, compression, head work, different fuel, balanced crank/rods, etc... Those engines are thoroughly worked over the best I can tell...

Funny thing is - you can just go buy a new R1 or zx-10r and have 150+ ponies with equal weight to our 600RR... And that's with no mods!

These liter bikes are getting so light I'm not sure it makes sense to buy a 600 anymore. Except for the Honda liter bike - which is also a pig.

But then you can't race in any 600 class....that's what I'm wanting the motor for....racing!

Full race exhaust and PCIII w/ custom map-$1500/10-15 hp
HRC Power up kit-$1300/5-6 hp
HRC VElocity Stacks and Air Filter-$500/3-5 hp
I wonder if this really would add up to 120Hp rear wheel?

I'm sure it would add up to $3000+.

I am building a CBR600RR up with the Exhaust, PCiii, HRC Power up Kit, and Velocity Stacks and will tune it on Ultimate 4 (makes less than MR1). i am not going to run the HRC ECU as i have heard of crank bearing problems when the CBR is being spun up to 18,000rpm

my 04 CBR600RR made 108hp with just a Two Brothers slip-on on our edddy current dyno, and i am shooting for 120hp at the wheel, but time will tell :cool:

But will the average rider be able to handle any of the new liter bikes.

Hey guys

I will let you in on a secret. I know Clarkie from www.apriliaforum.com

I am going to post a little of his bio so that you guys are aware we have one hell of a racer and engine tuner on board. he is a great source of info on the aprilia owners site....and we are lucky he has purchased a 600RR...

The Aprilia EMA "Clarkie" Project bike

Let us introduce you to the most Evil Aprilia motorcycle ever created... the "Clarkie". The Aprilia RSV Tuono "Clarkie" was built from a standard Tuono that had a wicked interaction with gravity earlier in the year. Sure the bike could have been fixed back to stock... but that would be boring. Thus the Tuono Clarkie was born. Named after the 2000 Aprilia Cup champion and Aprilia Demo Manager, Aaron Clark, the "Clarkie" features everything he wanted in the most twisted full-bore project bike Aprilia has ever had. Aaron ordered a pile of the coolest stuff available from his friends at European Motorcycle Accessories. A bike capable of squeezing the rider between the gas cap and the asphalt called for an all black (very very black) paint scheme -— so complimenting that scheme, the stock Brembo wheel and brake package was replaced with black superbike class PVM wheels, calipers, and rotors. If twisting the planet off it's axis was the goal, the addition of the Translogic QS2 Quickshifter makes it happen without clutching. The "Clarkie" barks through a Harris Performance slip-on, cranking out 130 horsepower and 80 ft. lbs. of torque to the rear tire. With the basics taken care of, it was time to control the evil one and only the best Ohlins shock and steering damper were up to the task. EMA is proud to sponsor the RSV Tuono "Clarkie" and help you build your own bike up to your high standards. EMA distributes only the highest quality components for your performance motorcycle.
Screw average... let EMA and Aprilia show you the way.

Hello

Check out the July issue of Road Racing world. There is an article about the HRC Formula Extreme Honda bikes. It has detailed information on the work that has been done to the race winning machines!

#1 item Al Ludington mentions is the Motec Engine Management system/Data acquisition system! He also mentions getting titanium valve buckets and also a Jardine Titanium exhaust system.

Good article for any of us 600RR owners!!!


Take Care
Ron
