Finally went for my first ride today on my Argyll Motorsports 2016 Yamaha YZ450FX!!!! All I can say is WOW!!!! Went to B3 Motocross track and within the first lap was in a total zone with the bike!!! What did I like about it? Where to start....the power is smooth yet incredibly strong and pulls forever!!! In ten seconds I could change the mapping from aggressive loamy to smooth hardback (read: fat, old guy map) with the power tuner!!! I never touched one thing on the suspension and yet we ran a 20 minute moto and I could do anything I normally do with my old bike with revalved and resprung suspension. The transmission on this bike is awesome for what I will use it for. 1st gear is low for those times I am following my 6 year old son on his PW50. 2nd is the same as the motocross bike, 3rd is a little lower, 4th is taller, and 5th gear.....never got anywhere near 5th!!! That hyperdrive gear is going to be saved for when I put this thing on the ice next winter!!! And did I mention electric start? Not sure the kickstart even works as I never pulled it out once. And with the 160 watt stator I can mount and power my 8" HID race light and bomb around the trails near my house after dark!!! This is the first time I can say that I went out for the first ride of the year and didn't have to come in due to incredible arm pump!!! And I've owned a lot of different bikes, from Honda CRF 250 and 450s plus CR250 two strokes, KTM 250SX and 525EXCs, Yamaha YZ 125, 250, 295 and 325 two strokes, YZ426 and 450 4 strokes.........truly this is the best bike I've ever owned hands down!!! Can't wait to add a few personal touches to this bike, it's going to be a great riding season with this machine!!! Thanks again Argyll Motorsports for guiding me to this purchase!!!
