TTR90 Model Year History and Changes
The TTR90 is a reliable, easy to ride bike from Yamaha. It has remained popular among bikers since its release in 2000, and as such, it has gone through several model year updates. Read on for an overview of the TTR90’s history, and some of its key changes over the years.
The Beginning
The TTR90 first debuted in 2000, and was designed to be an entry-level dirt bike. It featured a four-stroke, air-cooled 90cc engine with a five-speed transmission. Additionally, it had adjustable suspension that could be tailored to riders of different sizes and abilities. From the start, the TTR90 was a hit among new bikers who wanted an easy-to-ride bike that also had enough power to keep them entertained on their off-road adventures.
Model Year Updates
Since then, Yamaha has released several updated versions of the TTR90 over the years. In 2004 they released a “big wheel” version which featured larger 19″ front and 16″ rear wheels – perfect for taller riders or those who wanted more stability at higher speeds. In 2007 they released an electric start model which made starting much easier than before – no more kickstarting! They also added electric power valves to their engines which improved performance at lower revs while still being fuel efficient. Finally, in 2011 they released a YZ styling kit which allowed riders to customize their bikes with bright colors and graphics similar to those found on Yamaha’s YZ series motocross models
TTR90 Engine
Power and Performance
The TTR90 engine is capable of producing 9 horsepower at 7500 rpm and 8.5 ft-lbs of torque at 6000 rpm. That might not sound like a lot, but it’s more than enough power for small bikes like the Yamaha TTR90 and Suzuki DR-Z70. The TTR90 engine is also able to run on a variety of fuels, including regular unleaded gasoline, premium unleaded gasoline, and even E10 fuel (a mix of 10% ethanol and 90% gasoline).
Reliability and Durability
One of the things that makes the TTR90 engine so popular is its reliability. This engine is built to last, with many riders reporting that their bikes have easily gone 5000 miles or more without any major issues. Additionally, the TTR90 engine is relatively easy to work on, so you shouldn’t have any trouble performing basic maintenance tasks like oil changes and spark plug replacements.
Horsepower
The TTR90 engine produces 8 horsepower – enough to reach speeds of over 40 mph on flat surfaces. That may not sound like much, but when you consider that this bike weighs less than 130 lb., it’s an impressive amount of power for an engine its size. And, because it’s relatively lightweight, the bike can handle tight turns and sharp inclines without sacrificing speed or agility.
What is the TTR90 Top Speed
The TTR90 can reach a top speed of over 40 mph. It won’t win any races against bigger bikes, but it’s more than enough power to keep up with other bikes in its class. And since it has such great balance and control, you can easily navigate tight turns and steep hills without slowing down too much.
TTR90 Jetting:
If you want to get even more out of your TTR90 engine, you can adjust the jetting to suit your needs. Jetting allows you to fine-tune the air/fuel mixture in the carburetor which gives you better throttle response and improved acceleration without sacrificing fuel efficiency or power output. Of course, jetting should only be attempted by experienced riders who understand how carburetors work and how different jet sizes affect performance.
TTR90 Suspension
Front Forks
The front forks of the TTR90 are designed to provide a cushioned, smooth ride every time you hit the trails. They feature adjustable rebound damping as well as preload adjusters so you can customize your suspension setup based on terrain and riding style. The forks also have a large diameter tube with increased oil capacity that helps reduce heat buildup during long rides. This ensures consistent performance throughout your ride without any sudden dips in performance or comfort.
Rear Shock
The rear shock of the TTR90 is another great feature that adds an extra layer of cushioning to your ride. It features adjustable rebound damping and preload adjusters, so you can dial in your settings for a perfect setup every time. It also has a large diameter tube with increased oil capacity for greater heat dissipation, making it ideal for long rides on rough terrain. Additionally, its lightweight construction makes it easy to maneuver when making tight turns or climbing hills
Weight – How Does it Compare?
The TTR90 weighs in at about 27 pounds, which is pretty average for a dirt bike. However, what sets the TTR90 apart from other bikes in its class is its weight distribution. Thanks to its centrally located gas tank and low-profile seat, the TTR90 has a very low center of gravity. This makes it easier to handle, especially for beginner riders.
Reliability – How Long Will it Last?
The TTR90 is a very reliable bike. It’s built with quality components that are designed to last. Additionally, the TTR90 comes with a two-year warranty, so you can rest assured that your investment is protected.
TTR90 Handling
The handling of the TTR90 is second-to-none, which is why it’s become so popular among bikers of all experience levels. Its semi-knobby tires provide excellent traction on dirt roads, while its adjustable rear shock absorbers help keep your ride smooth over uneven surfaces. Whether you’re racing off-road or taking a leisurely Sunday drive, the TTR90 will give you all the control you need to stay safe and have fun!
Seat Height – What Size Rider Is The TTR90 For?
The seat height of the TTR90 is 28 inches, which means it can comfortably accommodate riders between 4’7″ and 5’5″. If you’re taller than 5’5″, you may find the seat uncomfortable after long rides. You can always adjust the suspension settings if needed, but the seat height itself cannot be adjusted.
Conclusion:
If you’re looking for an easy-to-ride dirt bike that offers all the bells and whistles of larger bikes without all the extra power, then look no further than the Yamaha TTR90. This lightweight motorcycle is perfect for beginners and experienced riders alike, as its adjustable suspension settings allow you to customize your ride experience. Plus, with its comfortable 28 inch seat height, it can accommodate riders between 4’7″ and 5’5″. So if you’re ready to start exploring off-road trails then check out the Yamaha TTR90 today!
