About Throttle Theory Powersports

Welcome to Throttle Theory Powersports, a rider-owned shop in Houston, Texas focused on clean preowned motorcycles, ATVs and side-by-sides, plus new youth go karts and golf carts.

We’re a small shop off Scarsdale & I-45, not a giant big-box store. That means straight answers, real fitment help, and no dealer games. Our goal is simple:
make it easy to buy a bike, quad or kart, and easy to keep it running with the right parts.

Preowned Motorcycles, ATVs & Side-by-Sides in Houston

Throttle Theory specializes in used motorcycles in Houston and budget-friendly ATVs and UTVs that are ready to ride, not projects.

You’ll regularly find:

  • Preowned street bikes, naked bikes and cruisers

  • Adventure and dual-sport motorcycles for Texas backroads

  • ATVs and side-by-sides for ranch, lease and weekend fun

  • Clean trade-ins and unique units you don’t see at cookie-cutter dealers

Every unit is hand-picked, checked over, and sold with a no fees – price + tax only mindset. No freight add-ons, no surprise “setup” or “doc” charges when you sit down to pay.

If you’ve searched for “used motorcycles Houston”, “ATV dealer Houston” or “UTV for sale near me”, we built this place for you.

New Youth Go Karts & Golf Carts

On top of preowned units, we also stock new go karts and golf carts for families who want fun that doesn’t require a motorcycle license.

  • Youth ATVs & 110cc quads for kids learning to ride

  • Youth and mid-size go karts with speed limiters and belts

  • Golf carts and neighborhood cruisers for campgrounds, subdivisions and properties

We spend a lot of time helping parents answer,

“What size go kart or ATV actually fits my kid?”

If you’ve been scrolling “youth ATV Houston,” “kids go karts Houston” or similar, we’re happy to walk you through sizing and options in person.

Your Local Source for Motorcycle & ATV Parts in Houston

Beyond units, Throttle Theory Powersports is aiming to be your go-to spot for motorcycle parts, ATV parts and UTV parts in Houston.

As a Parts Unlimited dealer with access to Yuasa batteries, we can source:

  • Motorcycle parts: oil filters, air filters, spark plugs, chains, sprockets, brake pads, levers and controls

  • ATV & UTV parts: tires, wheels, drive components, bearings, suspension and basic electrical

  • Go kart and golf cart parts: service items, tires, cables and common wear parts

  • Fluids & chemicals: engine oil, gear oil, coolant, brake fluid, chain lube, cleaners and detail products

Whether you searched for “motorcycle parts Houston,” “ATV parts near me,” “side by side parts Houston,” or “go kart parts Houston,” we can usually get what you need quickly through our distribution network.

Just send us your year, make and model and what you’re trying to fix or upgrade—we’ll match the right parts and give you a clear price and ETA.

Riding Gear, Helmets & Accessories

We also stock riding gear and accessories so you’re not riding in a T-shirt and work gloves:

  • Helmets (youth and adult)

  • Gloves, goggles and basic protection

  • Tie-downs, soft loops and ramps for transporting your bike or ATV

  • Phone mounts, grips and small comfort upgrades

  • Battery tenders, chain brushes and other maintenance accessories

If you’re picking up a new bike, quad or go kart, we can help you grab the helmet and gear you need the same day.

Service & Setup Support

For many of the units and parts we sell, we can also help with:

  • Oil changes and basic services

  • Tire mounting and balancing (where applicable)

  • Chain and sprocket installs

  • Brake pad replacement and fluid flushes

  • Battery testing and replacement

  • Accessory installs (handguards, phone mounts, lighting, etc.)

We focus on practical, real-world service for the kind of machines people actually ride in and around Houston—no pressure, no upsell.
