Tires: Michelin
Doing a trackday with your street tires is plain silly. Once the pace picks up youA'll want the confidence that only sticky tires provide, and the new Power One tires worked impeccably. Technically, these could be used on the street, and their dual compound construction (softer on the sidewalls than in the center) would let you get away with doing so, but their ideal environment is the racetrack. They didn't budge during our testing, and unlike the street rubber, these tires' grip levels weren't reached.

Exhaust: Graves
The full titanium exhaust knocked off 11 pounds while adding over ten horsepower. OK, so this pipe is super expensive, but it comes in stainless steel at a much more reasonable price.

Suspension: O-hlins
The quick and obvious conclusion we came to is that stock suspension just isnA't that good. It's fine for street riding and an occasional trackday, but if you're looking for the best ride possible, a rear shock and fork internals are imperative. The shock firmed up the rear enough to make the front end more planted, while the fork internals controlled the reactions to bumps and braking inputs with more precision than the stock forks. Combined, these upgrades allowed for more speed with tighter and more controlled lines.
O-hlins TTX shock $1300 (plus $800 for Graves tune)
O-hlins fork kit $1500 (plus $800 for Graves tune)

Fueling: Dynojet
The Power Commander V is an updated version of the popular fuel box we've all come to know and respect. One of its coolest features is the new AutoTune accessory that essentially takes care of creating the perfect fuel map. Once installed, the PCV and AutoTune work together and constantly alter the fuel map for the optimum air/fuel ratio.
Power Commander V: $359
AutoTune: $249

Conclusion
Though we generally try not to get too wrapped up with lap times and prefer seat of the pants and functional impressions for a lot of product testing, there was no scientific way to conduct this experiment without the clock ticking.
Our results were slightly different than anticipated, but valuable nonetheless. The full exhaust system scored not only the biggest difference in times but also perception. It was the definitive mod that cut significant time and also made the bike feel faster.
We expected the sticky tires to make a huge impact and they did, but once suspension and grip come into play the search for the perfect setup can become elusive. Hell, the pros spend all year getting a bike dialed, and we surely werenA't going to sort it perfectly in a day or two.
Each and every modification made a noticeable improvement, but it was the exhaust that would be the most immediate and valuable investment for street riders.
