The weight of the bike and rider need to added to actually calculate power to weight!!

SV- 390lbs+165lbs rider=555lbs/70hp=7.93lbs per hp
RS125- 160lbs+165lbs rider=325lbs/38hp=8.55
BMW- 430lbs+ 165lbs rider=595lbs/101hp= 5.89 lbs per hp


You really don't think the RS125 is the most powerful!
SV- 390lbs/70hp=5.57lbs per hp
RS125- 160lbs/38hp=4.21lbs per hp
BMW- 430lbs/101hp=4.26

I forget how it was exactly worded, but XSeal said it best, if it is the bike to beat, g buy one.  Again, it is a very easy bike to ride, just hard to go fast on.


No SV I have ever raced agist has been 390lbs. 

N8!

I am going to volunteer myself to race Ed's superbike next year.  Of course I am a young female with pigtails and no racing experience...but I should be out there beating all the LW guys in no time...I think not.  The guy is fast.  Plain and simple.  So next year I'm borrowing his bike and I'm going to be fast to.  Yeah right...

Ok I can't look at this any longer.  It always seems that when ever someone talks about Nates HP to weight ratio there is a mixed bag of dynojet and factory hp measurements.  To compare motorcycles we will leave the rider out of the equation and use the same dyno numbers.  A race prepped first gen SV650 weighs about 365.  With a 1mm SS prepped engine makes 74hp on race gas on a dynojet.  That same bike on a factory dyno makes 66hp that is approximately a 12% reduction in measured hp.

The numbers for Nates bike as reported in RRW is 445lbs and 101.6hp.  Now lets redo the calculations
using the same hp measurements

Using a Factory dyno:
SV  365 / 66 = 5.53 lbs per hp
BMW  445 / 101.6 = 4.3799 lbs per hp

If the sv weighs allot less than stock... say 300lbs
SV 300 / 66 = 4.54

How about a good running SV Super bike

SV = 325 / 84 = 3.869 Lbs per hp

I am assuming that people are upset about the CCS regional races, and that Nate's bike is always run in ASRA TBike configuration.  Well the bike has a power to weight advantage against a Super Sport SV, but not against a good SV super bike. He still is not meeting the 4 to 1 ratio for ASRA.  No matter what, wrestling 445lbs of motorcycle is not physically easy.  That bike has to push allot more air than any SV.  Nate is a very good rider, but both Nate and Ed can be beat.  It will take a good bike and allot of riding skill.

If the people who are upset about a bikes legality continue to speak their mind here instead of to Kevein Elliot, nothing will get done.  Racing is about competition, if things are unfair, it is up to the racers to bring it to the attention of the sanctioning body in a professional manner.  If you tell them they are not doing their job and they are idiots, you will not get very far.  If you approach them calmly and discuss the issue diplomatically with facts, not opinions, things will get changed.  You as a rider have three choices:

1) Complain and do nothing.
2) Do something to change the rules.
3) Get better and beat those guys.

For those of you who want to complain and do nothing, the way I see it, if you do not want to be measured against others go do track days and tell your friends that you are fast.
