Seriously depending on what increase you want there is many things that can be done. Just getting the handling dialed in and the clutching spot on can make this a fun sled to ride. It will out handle just about anything available. If you want in the 10 to 15 hp upgrade simple intake, exhaust and pipe combos will do that for under $1000. EVO flashes are making strives also. Raising the rev limiter to clutch a bit higher and get into the meat of the power band.
BUT ultimate is the TURBO it is just unbelievable when you have 230 to 260 hp at your fingers and run down normally aspirated sleds at will!!!!!!!!

You can max out Na, but you can keep spending money, just ask cannondale.A free turbo.....
Seriously though, you can invest in a header, air box mod, can, clutching and flash an get the same results as the trail turbo, but the cost isn't really all that different. with the NA approach, you max out. With the turbo, you can keep spending money and have even more boost!

This viper's got at least 6000km on her, seriuosly though they do loosen up quite a bit with miliage


Never Maxed out. Always something to try! As long as it's just bolt ons don't lose any ride time other than fine tuning. Only lost fun factor once. Every year I don't buy a new sled mods are just a fraction of $ that otherwise would be spent.You can max out Na, but you can keep spending money, just ask cannondale.
