2011 Yamaha YZ85 Ride

Watch the YZ85 and it scream around the track in our Yamaha YZ85 First Video .

I was only 10 years but I can still remember like it was My dad and I made a trip to the local dealer to pick up some for my five-year-old YZ80. As we entered the I was instantly drawn to a lineup of 1982 YZ’s. I quickly my way down the row of bikes, skipping the 490, then the 250, the 125 and finally to the new YZ80.

The bike was ahead of my current ride. It a mono-shock swingarm, liquid via a small radiator behind the number plate, a seat actually carried up onto the and was decked out with black plates all sporting a big #1. The bike was at the of mini technology and was the ride of for all of the fast kids who were the mini class.

I could sat and stared at that bike for on end. For months I would about owning it, but a new bike was not in our and I would have to wait a while, almost 30 years, for a new YZ80 to show up in my garage.

I have a 2011 YZ85 in my garage. Unfortunately, I am now way too old and too large to my youth, but at least I get to watch my own son put the YZ through its paces. A lot has changed in all years but one thing still the same; the YZ85 is still a contender in the mini ranks.

MotoUSA test rider Chamberlain says the YZ85 has of engine power. The trick is to ride high in the rpm range.

For young riders between the of 9 and 14 who are looking to make a name in the world, or at least bring some trophies from the track, the Yamaha has the engine to do it. The YZ features an 85cc liquid-cooled, reed-valve-inducted two-… engine. The bore and … measure up to x 47.8mm with an 8.2:1 ratio.

Fuel is fed through a Keihin flat-slide carburetor and is put to the ground via a six-speed close-ratio

While the spec sheet on the 85 is groundbreaking, the performance output is This bike flat although the lack of a power creates a very hard motor with most of the delivered in the top end, even by 85 In addition to its anemic bottom end and power, the YZ comes with tall gearing which it even more difficult to the power in tight or slow riding areas.

Beginning could become frustrated to keep it in the powerband, but aggressive who can ride at the top of the rev range will be satisfied with the results.

We at a variety of MX tracks resulting in engine feedback from our 90 pound test rider, Chamberlain. Our first testing was a very tight track lots of steep elevation

“I had a hard time used to the power and had to really the clutch a lot to get it to pull out of the tight and up the hills,” said Luke the first session. The tall also took a little to get used to. “I had to run a gear than on my current 85 in all of the turns in to keep it in the powerband.” By the end of the day he had figured out the new points and got a better feel for the delivery. I could tell his areas of frustration were and he was starting to really enjoy the new

As we were getting ready to up at the end of the first day, the track and local pro, Devin asked if he could take the YZ out for a spin. While he was a little big for the I was curious to get the feedback from of his riding level. During the lap I could hear a lot of clutch but by the second lap all I could hear was a two-… echoing through the

After a few laps he pulled in with a big grin on his face. this thing feels as as some of the 125s I was riding a few years back!” That like a pretty good to me.

The YZ uses a single left-side shroud. Wider, faster suit the Yamaha’s stock and power delivery.

Our next two tracks featured a more motocross layout with higher speed corners and fast straights. Luke away with a much appreciation for the motor at these “It was much easier to it in the power on the big tracks. I was able a lot more corner speed and the revs up much easier. It was fast down the straightaways.”

The transmission performed flawlessly any missed shifts or false While the final drive is a tall for some locations, the gear ratios seem suited. The clutch is smooth, the lever pull is a little than Luke would

The clutch engages at the end of the lever makes quick fanning to do without having to pull the all the way back to the bars.

Even slightly stiff suspension for our rider, the YZ85 is a great

Chassis / Suspension

The YZ uses a semi-double-cradle steel frame. The subframe is removable to allow maintenance and cheaper replacement Ergonomics are roomy enough for kids to remain comfortable and the is very flat and fairly allowing the rider to easily up on the front for cornering. Handlebars are in relation to the seat and with a height of 34 inches, taller will feel the most on the Yamaha.

Unlike its larger that use ProTaper bars, the 85 stock with steel that are very susceptible to during a crash. The bike is slim with the single radiator tucked in nice and The right side uses an fuel tank to compensate for the of radiator.

While still pleasing to at, the missing right shroud saves the hassle of having to with, or replace a cosmetic

The front suspension is handled by Kayaba inverted cartridge They offer 10.8 of travel and have fully compression and rebound dampening. tubes and internals are low-friction for a ….

Out back is a Kayaba providing 11.1 inches of Just like the fork, the has fully adjustable compression and

Our tester stands at 5’2” and the YZ very comfortable for his size. It like the YZ still has a little left for that next spurt. With Luke in at a scant 90 lbs. the springs are on the stiff side. We try to set rider sag in the — 105mm range on with free sag ending up in the -45mm range. On the YZ, setting sag resulted in a little too much sag.

Slightly softer would get the settings more in with where we typically but Luke liked the stiffer when landing big hits than the setup on his own bike.

and Maintenance

While there is no technology appearing on any of the 85’s days, Yamaha has continually the littlest YZ into a well out and competitive race package. are also a few little details most mini dads appreciate. The airbox opening is roomy and the filter is easy to both on the cage, as well as the airbox. The chain adjusters are easy to use and are easily readable for adjustments.

Both of these little go a long way in simplifying the maintenance on the bike. They also young riders to learn tasks without the worry of something wrong, like installing an air filter and cross the air filter bolt. The clutch also uses a two-piece for quick and easy access to the

What We Would Change

will have some to grow with the tallish YZ. We can basic maintenance to the kids easy airbox and chain access. The stock handlebars bend in the smallest tip-over and to be replaced.

The YZ85 is a ripping bike right out of the crate. The adjustable suspension works without modification, with the exception being that of the proper spring rate. The has plenty of muscle and it just a matter of getting it dialed in for the you are riding.

If we were to race bike on our typical tracks I add a couple teeth to the rear (47 stock) to give it a little grunt out of corners. I would be interested to see if an aftermarket pipe and a VForce reed block add any usable power to the midrange sacrificing too much of the awesome on top. Playing with the timing may also add a little usable power down

Other changes would be component swaps. The bars be the very first item to get out, as they are a big liability, in the simplest of crashes. Break-away are always a great idea for any bike, especially one ridden by youngsters. The pegs on the 85 are not like the wide ones that on the larger YZ’s and we’d to a wider peg as well.

The stock Dunlops work on terrain but lacked the lugs for anything on the softer side. All of are simple aftermarket upgrades most racers would regardless of the bike.


With quite a few days on the YZ, our tester is really falling in with the power of the little 85. it took a bit to get used to the top-end he has adapted well to the engine The roomy ergos fit him well and a little room to grow. He likes jumping the YZ and is very with how well it soaks up any landings.

The only problem at point will be telling him the is over and we have to give the back to Yamaha. Looks I might have to start up.
