RPM Information: 5000
Your engine's RPM range is important in choosing the right propeller for a given application. For example, if you look at your tachometer at top speed and it is not within the engine's RPM range then that is generally not good. You want your RPM's to be within the proper range while at wide open throttle (WOT). Be sure to do your testing under your normal boating conditions and with a good propeller (not bent, cracked, or excessively chipped). more

7 1999 YAMAHA YZ250
Through most of the ‘90s, the YZ250 was solid and reliable, but not quite fast enough to win magazine shootouts. The 1999 model wasn’t that much better when it came out, but it was the first year of the motor configuration that is still produced today. It was easy to get more power out of the YZ and the handling wasn’t half bad. To this day, there are lots of YZ250s from the ‘90s still running well.

5 1996 HONDA XR400R
Honda built this bike especially for Scott Summers. Unfortunately, Scott was so much in love with his XR600R, he never gave the 400 a second look. But everyone else loved it. The Honda was easy to ride and just light enough to be a great woods bike. It even made a mark in motocross, with Spud Walters getting on the podium in the National Four-Stroke Championship series (Yes, there was one of those back the). After two years it was overshadowed by the arrival of the Yamaha YZ400F in 1998, which changed expectations for four-strokes forever. Interestingly enough, the XR400R is much more desirable as a used bike today than those early YZ400Fs, and many more XRs are still in use. here

Remember the ‘90s? We do. Ron and Tom are still wearing most of the same clothes. What set that decade apart from earlier years in motorcycle history was that many dirt bikes had reached their prime. The rapid evolution of suspension and brakes had slowed down. For the most part, a good bike of that era is still a good bike today. Several of them are still available as new bikes, in pretty much the same form. Others are gone forever and we miss them dearly. Here our our picks of the 10 best ‘90s bikes that we would still enjoy today. We choose MX, off-road and dual-sport bikes without bias, but we have to admit that off-road bikes have stood the test of time better than motocross models. We also gave no advantage to bikes that were historically important. The 1998 Yamaha YZ400F and 1997 Honda CR250R, for example, were significant, but not that much fun to ride. These were.

If there was ever a case of not appreciating what we had, this is it. The Kawasaki KX500 was a truly great desert bike, but it was sold as a motocrosser. On the track, it was brutal and demanding. It was discovered as a Baja/desert bike in 1987 when Team Green hired Larry Roeseler. The KX then won every Baja 1000 between 1988 and 1997. The bike hardly changed in that period. In 1990 it got an upside down fork and in 1992 it got a new crank and ignition. Then it was unchanged until 2004, when the last one rolled off the assembly line.

3 1992 Kawasaki KX500

6 1995 KAWASAKI KDX200
We lost this bike back in 2006 and it’s never really been replaced. The Kawasaki KDX200 was a pro ISDE bike in the hands of someone like Jeff Fredette, or it was a sweet entry-level trainer. There was nothing it couldn’t do and make its rider smile. It went unchanged from 1995 to the end. There was also a KDX220 that was almost the same motorcycle (with a bigger bore and a smaller carb) between the years of 1997 and 2006. If you find one of these in good shape, never let it go. For a complete history of the KDX200, click here. here

In the USA, the price rose modestly to $2490 for 2012 and to $2599 for 2013-17. Canadians were asked to pay $3079 in 2012, but the MSRP dropped to $2599 (2013) before rising to $2799 (2017).

Virtually all new for 2012 (but quite similar looking) is the Zuma 50F. This new Zuma features updated styling and a four stroke motor, which was a shock to tuning enthusiasts. Despite the full overhaul and new engine, Yamaha retained the YW50 model code for this third generation. [links]

[biohacker]

With the third generation, the styling is all new but the changes are subtle. Some tweaks were made that increase its stylistic ties to the larger Zuma 125. The bug eye headlights are still present but most other parts are new. This new model has awesome lines on the rear end with a more sculpted and flowing shape that improves upon its already nice predecessor. The red rear shock spring and front caliper are nice touches.

Over that time the Zuma has gone through two model codes (CW50, YW50), three generations, and a huge number of names (Zuma, Zuma II, Zuma 50F, Zuma 50FX, Zuma X, BWs, BWs 50, BeeWee). The sections below discuss each of these generations.

Moreso than any other modern scooter in North America, the CW50 kicked off the aftermarket performance scene. The scooter used a vertical Minarelli motor, for which aftermarket parts were widely available globally and thus a new era of scooter culture was born with countless scooterists installing big bore kits and faster exhaust pipes. These parts are still widely available today, such as from ScooterTuning and ScooterSwapShop.

The other downsides of the YW50 are the inherent ones that come with having a 2-stroke engine. A lot of scooters are 2-strokes so it’s not really fair to bring this up, but the YW50 is being sold in a day when most scooters are shifting to 4-stroke engines (The Zuma was the last 2-stroke 50cc from a Japanese manufacturer). Being a 2-stroke, you get great power but you also get reduced fuel economy, increased pollution, you have to buy 2-stroke oil and the engine life is shorter. If you want a 2-stroke scooter you’ve probably already got your mind made up and I can certainly understand why. Read more about 2-stroke vs. 4-stroke engines here. [links]

After Hannah broke his leg at the end of the 1979 season, Mike Bell won his lone Supercross title in 1980, Broc Glover raced and won on the 250 from time to time, although he was more closely associated with the YZ125 and YZ490.
Rick Johnson’s success was legendary, but only the early years of it were with Yamaha and the YZ250. After he left, there was a void left that didn’t get filled until Damon Bradshaw came along. The most striking thing about Bradshaw’s career was his ability not to win championships despite winning races. He still sits in 11th place on the all-time Supercross win list, but doesn’t have a single national title to his credit.

both worlds. It has won three GNCC championships with Ed Lojak, Fed Andrews and Barry Hawk. It won two National Enduro titles with Randy Hawkins and Ty Davis; three WORCS championships with Davis and Nate Woods; seven National Hare Scrambles Championships with Jason Raines and Doug Blackwell, and it even contributed to a National Hare and hound title with Ty Davis, who rode the 250 in select events.
If you go strictly by the numbers, the YZ is more of an off-road bike than a motocrosser. It has 15 off-road championships and only 14 motocross titles. Add them all up and the YZ is the winningist cross-platform racer in America.
THE YEARS
1968: Yamaha introduced the DT-1 250 two-stroke and everything changed. Before that, no one would consider racing a Japanese bike professionally. Even though that first model was no racer, it became a platform for various racers because it was light and reliable. European motocross bikes would still rule, but their days were numbered. more

2014: After years of small changes, mostly as hand-me-downs from four-stroke development, Yamaha reopened the YZ250 cold case file. They ran the numbers and figured that new bodywork was justified. Thus, the YZ got a facelift, along with suspension changes.

[jef.blanc]

1974: The first YZ250A was introduced. This was based on the bike that Gary Jones had used to win the 1971 National Championship, which was actually derived from his Top American status in the Inter-Am series. According to legend, Don Jones had shipped the bike to Japan with “A2Z” written on the tank, meaning it had everything modified from A to Z. Jones had made a new frame, cast his own engine cases and strapped on a CZ alloy fuel tank with bridal tack. When the bike arrived, it was redesignated the YZ because all Yamahas models began with a Y. But it was remarkably true to what Jones had built, right down to the strap on the tank. here
