Yamaha YZ450F top speed of 90MPH + Is it possible?
2014年6月7日 · Is it possible to get a top speed of 90 mph to 100 mph from a new YZ450F? If so, what size sprockets would be needed? Not sure about a standard 2014 but our Will Power tuned 04 can do 92 mph on 15/39 sprockets - that's running 17 inch wheels though.

YZ250F stock top speed???? - WR250F/YZ250F/YZ250FX
2004年8月27日 · 7143 fpm = 1.352 mile/min = 81 mph. This would be the theoretic top speed with zero slippage. This is very interesting calculations because my GPS calibrated Watchdog computer shows my 250F as consistantly hitting 76 mph top speed with a 110/90 rear on gravel. I have also run a 75+ mph on ice with a studded 100/90.

yz450f road gearing and top speed - ThumperTalk
2010年3月12日 · It was geared for motocross where the high top speed was not that important. I run a 16 on the front and a 45 on the rear for my road setup, but I am not concerned with going that fast either. My buddy has a YZ 426 that is a 5 speed and he has much more top end.
All YZ450's 4 speed?? - YZ400F/426F/450F/450FX - ThumperTalk
2005年6月26日 · But most people totally misunderstand the YZ450 4 speed. The 4 spd covers roughly the same overall range of speed as the 426 5 spd did, but with wider gear spacing. If both bikes are geared with identical final ratios in 1st, there's only about 3 mph difference in the top speed at the rev limit. You just don't have to shift so much.

Gear ratios of 06 comp to 05 and WR? - ThumperTalk
So, the '06 YZ has the same 1st gear as it did with the 4 speed (slightly lower than the YZ426), and the same 2-5 as the YZ426 did. If you re-gear at the final drive so that low is the same as the old 4 speed (remember, the primary ratios are different), …
2007 yz450f top speed at reasonable rpm - ThumperTalk
2016年11月1日 · That would reduce the top speed to about 80, and at max RPM. 60 MPH produces about 7000 RPM on pavement, and 70 is a smidge over 8200, and again, 5-8% wheelspin should be expected. Not wonderful for any kind of extended period.

2003年2月6日 · Good point WFO, but even with the 15/44 top speed is "only" 90. As was mentioned, when Ty raced the 426 on a few occassions at least he used the WR fifth gear (may have used fourth also to match the dogs on fifth) to keep up with the 500s in the more open races.
