Actually the VP Ultimate 2 and/or Ultimate 4 is the best stuff. They advertse the 2 being for 2 strokes and 4 being for 4 stroke's but our rep said it was the exact same, just labled different for marketing. You will definatly notice a difference with these fuels, and an even bigger difference if you map/jet specificaly for them.

One of the mags did a comparo last year on these race fuels and the performance gains varried between bikes... i.e. fuel A produced better performance on the R1 over fuel B, but on the GSXR fuel B did better than fuel A.

If you're concerned with getting every ounce of performance, you need to dyno test each fuel and map for each fuel.

waste of money. unless you are racing, or you have done engine work and bumped up the compression enough that it is required. I wouldn't bother spending $5 a gallon on race gas.
