If you've been looking at the husky tc 105, you already know it occupies a pretty weird, but awesome, niche in the dirt bike world. It's not quite a full-sized 125, but it's a massive step up from a standard 85cc mini. For kids who are outgrowing their small bikes but aren't quite tall enough to manhandle a full-sized frame, or for the Supermini class racers looking for every bit of legal displacement they can get, this bike is essentially the holy grail.
I've spent some time watching these things scream around the track, and honestly, there is something visceral about the way a 105 sounds. It's got that high-pitched two-stroke "zing," but with a deeper, more aggressive throatiness that tells you it's got a bit more meat on its bones than a standard 85. Let's dive into what makes this machine tick and why it's become such a cult favorite in the pits.
The Heart of the Beast: That 105cc Engine
The transition from an 85cc to a husky tc 105 isn't just about a slightly bigger piston. It's about how that power is delivered. When you bore and stroke an engine to hit that 105cc mark, you change the torque curve significantly. On a standard 85, you're often hunting for power, clutching the life out of the bike to stay on the pipe. With the 105, you get this surprising "grunt" off the bottom.
It's still a small-bore two-stroke, so don't expect 450-style lugging, but it's much more forgiving. If you mess up a corner and drop your RPMs slightly, the 105 has the guts to pull you back up into the powerband without requiring three frantic downshifts. For a young racer, that extra displacement provides a massive confidence boost when they're trying to clear doubles that were previously just out of reach.
Handling and the Chassis Feel
Husqvarna has always been known for that "premium" feel, and the husky tc 105 (usually built off the TC 85 platform with a big-bore kit) carries that reputation well. The chromoly steel frame is a work of art. It's designed to flex in just the right places to soak up the chatter of a rough track while staying stiff enough to track straight through deep ruts.
The bike feels incredibly light. Because it's essentially an 85cc chassis, it's flickable in a way that a 125 just isn't. You can change lines mid-corner with a simple flick of the hips. For riders who aren't quite 130 pounds yet, having a bike that doesn't feel like it's taking them for a ride is huge. The WP XACT suspension is another high point. It's air-sprung in the front, which makes it super easy to tune for different rider weights without having to swap out expensive springs every time the kid has a growth spurt.
Is It Just a KTM in White Plastic?
We have to address the elephant in the room. Yes, Husqvarna and KTM are siblings. The husky tc 105 shares a lot of its DNA with the KTM 105 SX. However, there are some subtle differences that fans of the Swedish-turned-Austrian brand swear by.
The most notable is usually the subframe. Husky often uses a composite carbon-fiber subframe which provides a slightly different flex characteristic compared to the aluminum ones found on KTMs. Some riders say it feels a bit "plusher" on the backside when things get choppy. Plus, let's be real—the white, blue, and yellow color scheme just looks classy. There's a certain "cool factor" to pulling up to the gate on a Husky that the orange bikes sometimes lack just because they're so common.
Who is the Husky TC 105 Actually For?
This isn't a bike for everyone. If you're a 180-pound adult, you're going to look like a circus bear on a tricycle, and you'll probably blow the shock out in a week. But for the right person, it's perfection.
- The Supermini Racer: This is the primary demographic. If you're racing in a class that allows up to 112cc, running a stock 85 is like bringing a knife to a gunfight. The husky tc 105 gives you the displacement to compete with the big dogs.
- The "In-Between" Kid: We've all seen that kid who is too fast for the 85cc class but looks like he's riding his dad's bike when he jumps on a 125. The 105 fills that gap. It teaches them how to manage more power without the intimidating physical size of a full-frame bike.
- The Hard Enduro Hobbyist: Believe it or not, some shorter adults or woods riders love these things for tight, technical trails. The power-to-weight ratio is insane, and it's easy to manhandle when you're stuck in a rock garden.
Living with a High-String Two-Stroke
Let's talk about maintenance, because a husky tc 105 isn't a "set it and forget it" machine. It's a high-performance racing tool. You're going to be mixing gas and oil (premix for life!), and you're going to be changing air filters after every single ride.
Because the engine is bored out and running higher tolerances, you really have to stay on top of your top-end rebuilds. Depending on how hard you're pinning it, you might be looking at a new piston every 20 to 30 hours. It sounds like a lot, but that's the price you pay for this kind of performance. The good news is that working on these bikes is a dream. There's so much room in the frame, and two-strokes are simple enough that most parents and kids can do the work together in the garage on a Tuesday night.
The Cost of Entry
Buying a husky tc 105 usually means one of two things: you're either buying a TC 85 and installing the factory 105cc big-bore kit, or you're finding one that's already been built. Either way, it's not the cheapest hobby. Husqvarnas carry a bit of a price premium over some of the Japanese brands, but the resale value stays remarkably high.
Since these bikes are so specialized, there is always a market for them. When your rider finally hits that growth spurt and is ready for the TC 125, you usually won't have much trouble finding a buyer for the 105. People are always looking for well-maintained Superminis.
Final Thoughts on the Ride
At the end of the day, the husky tc 105 is all about the smile under the helmet. There's a specific feeling you get when you're on a bike that fits you perfectly and has just a little bit more power than you expected. It's that feeling of "Oh man, I can actually clear that jump now."
It's a bike that encourages you to be aggressive. It rewards late braking and keeping the throttle twisted. While the 85cc bikes are great for learning the ropes, the 105 is where things start to feel "real." It's fast, it's loud, and it's arguably one of the most fun platforms Husqvarna has ever put their name on.
Whether you're chasing a trophy in the Supermini class or just want the ultimate woods weapon for a smaller rider, the 105 delivers. It's got the heritage, the tech, and most importantly, that "get up and go" that makes motocross so addictive in the first place. Just make sure you've got a fresh bottle of Maxima and some clean filters ready—you're going to want to spend a lot of time on this one.
