Took my bike out for a top speed run today. My bike is dead stock, I come in at 6' and 265 lbs. I wasn't trying to duck wind or anything going very slightly uphill(might as well call it flat). I new it would be good when first took me almost to 30, as I shifted into 5th I was passing 50(not all the way in it). Next time I checked gps it was clicking off 74-75-76, last time I looked before letting off I hit 80. That's damn fast on a stock atv. As per the safety guys, it wasn't the brightest thing to do but I did have on my helmet. Wonder how close the gps speed is. What's the fastest claimed speed on the XX?
