If you've spent more than five minutes on a track or a rough trail, you probably know that the stock ttr 110 rear shock leaves a lot to be desired. Yamaha built this bike to be a reliable, easy-to-ride machine for kids, which is great for its intended purpose. But let's be real: most of these bikes end up in the hands of "big kids" or aggressive young riders who want to send it over jumps and through whoops. When you start pushing the TTR 110 past its comfort zone, that factory rear shock starts acting like a pogo stick, and not in a fun way.
Upgrading the rear suspension isn't just about making the bike look cool with a shiny reservoir sticking out. It's about keeping your back from aching and ensuring the rear tire actually stays in contact with the dirt. If you're tired of bottoming out every time you hit a bump larger than a pebble, it's time to look at what's actually going on back there.
Why the Factory Shock Struggles
The main issue with the original ttr 110 rear shock is that it's basically a sealed unit with a very soft spring. It's designed for a rider who weighs maybe 80 to 100 pounds and is just cruising around the backyard. Once you put a full-grown adult on there—or a fast kid who is starting to clear doubles—the damping just gives up.
Damping is what controls the speed of the shock's movement. Without enough of it, the bike bounces back up way too fast after a hit. This is what we call the "bucking bronco" effect. You land a jump, the shock compresses all the way to the bumper, and then it fires you back up into the air. It's sketchy, and it's a quick way to find yourself tasting the dirt. Plus, the stock spring is usually too soft, meaning you're riding too low in the stroke, which messes up the bike's geometry and makes it handle like a wet noodle.
Choosing the Right Aftermarket Replacement
When you start shopping for a new ttr 110 rear shock, you'll realize there are levels to this game. You can go the budget-friendly route, which is still a massive upgrade over stock, or you can go full "pro" with high-end race gear.
The most popular choice for many pit bike enthusiasts is the DNM shock. It's a solid middle-ground option. These shocks usually offer adjustable rebound, which is a game-changer. Being able to turn a clicker and slow down that "pogo" effect makes the bike feel much more planted. They also come with different spring rates, so if you're a 200-pound guy, you can actually get a spring that supports your weight without sagging halfway through the travel just by sitting on it.
On the higher end, you have brands like Elka. If you're serious about racing or you just want the absolute best ride possible, an Elka Stage 3 is usually the gold standard. These are custom-built to your weight and riding style. They offer much better oil flow and heat dissipation, which means the shock won't "fade" and get soft after twenty minutes of hard riding. Of course, they cost more, but the difference in feel is like night and day. It transforms the TTR 110 from a play bike into a legitimate mini-moto machine.
Heavy Duty Springs vs. Full Shock Replacement
Some people try to take a shortcut by just putting a heavy-duty spring on the stock ttr 110 rear shock. I get it—it's cheaper. A BBR heavy-duty spring is a popular choice here. While this helps with the bottoming out issue, it actually makes the "pogo" effect worse.
Think about it: you now have a much stiffer spring trying to push the shock back out, but you still have the same weak, stock damping trying to hold it back. It's like putting a bigger engine in a car but keeping the bicycle brakes. It works to keep you from bottoming, but the ride quality is going to be harsh and bouncy. If you're on a super tight budget, a spring is better than nothing, but if you can swing it, a full shock replacement is always the better move.
Installation Isn't a Nightmare
One of the best things about working on a TTR 110 is how simple everything is. Swapping out the ttr 110 rear shock is a job you can definitely do in your garage with some basic tools. You'll need a way to get the rear wheel off the ground—a center stand is perfect—and usually just a few sockets and wrenches (typically 12mm and 14mm).
You usually have to remove the seat and the side plastics to get clear access to the top bolt. Once the bike is supported and the weight is off the swingarm, you just pop the top and bottom bolts out, and the old shock slides right out. Pro tip: while you have the shock out, take a second to look at your swingarm bearings. If they're dry, throw some grease in there. It'll make the whole rear end move much smoother. When you put the new shock in, don't forget to use a little blue Loctite on the bolts. You don't want your suspension vibrating loose mid-ride.
How to Dial in the Settings
Once you've got your new ttr 110 rear shock installed, don't just go out and pin it immediately. You need to set it up for your weight. This starts with "sag." Sag is how much the bike settles when you're sitting on it. Ideally, you want the bike to drop about two inches when you're in your riding gear. You adjust this by turning the preload rings on the shock body to tighten or loosen the spring.
After sag is set, play with the rebound clicker. If the bike feels like it's kicking you in the butt after a bump, slow the rebound down (usually turning the clicker to the right, or "slower"). If it feels like the shock is "packing down"—meaning it stays low and doesn't recover before the next bump—speed the rebound up a bit. It's all about finding that balance where the bike feels controlled but not stiff.
The Difference it Makes on the Trail
It's hard to overstate how much a better ttr 110 rear shock changes the experience. Suddenly, you aren't wincing every time you see a root or a jump landing. The bike feels taller, more stable, and way more predictable. You'll find yourself carrying more speed through corners because the rear tire isn't skipping over every little chatter bump.
If you're riding with friends who have stock suspension, you'll notice you're much less fatigued at the end of the day. Your legs and back aren't doing all the work that the shock should have been doing in the first place. It makes the bike feel like a "real" motorcycle rather than a toy.
Maintenance and Longevity
Unlike the stock unit, many aftermarket ttr 110 rear shock options are rebuildable. This is a huge plus. Every year or so, depending on how much you ride, you can have the oil changed and the seals replaced. This keeps the performance fresh. Even if you don't do a full rebuild, keep the shock shaft clean. If mud and grit dry on the shaft and then get sucked into the seals, you'll end up with a leak. A quick spray with a hose after a ride goes a long way.
Wrapping It All Up
At the end of the day, the ttr 110 rear shock is arguably the single most important upgrade you can make to these bikes, especially if you weigh more than 120 pounds. Whether you go with a simple DNM for backyard fun or an Elka for serious pit bike racing, you're going to wonder why you waited so long to do it. The stock shock is fine for learning the ropes, but once you're ready to actually ride, the suspension needs to be ready too. Grab some tools, swap that shock out, and go enjoy a bike that finally handles the way it should.
