First race was against a stock 660 raptor and well lets just say I beat him pretty bad. Next race was against a pretty heavily modded 660r. I can say he had full exhaust, intake, and jetted at the least. He also had 450r suspension and more. Me and him were pretty much neck and neck, I had him by about 1/2 a bike length. We raced two times same thing each time. Next race was against a piped only 2005 yamaha 450. I beat him by 3 lengths both times we raced. He had nothing to say about it. Next race was against a 2006 honda 450 with an hrc kit on it. He was bragging about how fast it was so I raced him too. I beat him the first time by like 5 lengths and then we did one more and I beat him by about 3 lengths. He was very shocked to see how fast the predator was. One of my last races was against the same 700r I had lost to when my bike had the hardrock intake mod. He has a full exhaust and k@n filter. Last time we raced he waxed me bad. This time we raced quite a few times and he beat me by about a 1 length each time. I was pretty stoked that my tuning had made such a difference. On a side note each race was on the street from a first gear roll. I had to roll into the gas in first and second because the front came up hard everytime. Needless to say I was very happy with the results of the races. I raced alot today and didnt even mention a few of my races. I only lost to one though!!!!!!!!!! All quads were fast and all gave me respect for my predator. The dude in the honda was really blown away, and said that he never knew the predator was that fast. I know everyone is gonna say it had to do with rider but like I said they were all on the pavement so no EXCUSES. Damn 700r was fast!!!!!!!
