The TM 24-125 is a great mid-size dirt bike. It has a High-performance 125cc 4 stroke 8.3hp gas engine with kick start, a top speed of around 55mph, and a seat height of 32”.

The TM24 features a 4-speed semi auto transmission with front and rear disc brakes, and a heavy-duty frame built for durability!

The bikes' full on motocross ergonomics and race suspension system make handling feel natural and unforced, and help it navigate over almost any type of terrain. Electronic CDI ignition makes kick starting effortless, keeps the bike running smoothly in all gears and provides a broad, even power band. And at only 161 pounds, the 125cc engine can propel the motorcycle to speeds of 55 miles per hour.

Add a Helmet. Sorry, at this price, the free helmet is not available for this model.

Frequently Asked Questions

When will my order be shipped and how long does delivery take?
Orders containing in-stock items typically ship within 3–5 business days. Orders that include assembly will require 7–10 business days to prepare. Please note that during the holiday season (Thanksgiving through Christmas), processing times may be longer due to high order volume. Once your order has shipped, you’ll receive an email with tracking information. Most orders are shipped via Less Than Truckload (LTL) freight and generally arrive within 3–7 business days. Deliveries to remote areas (such as mountains, forests, valleys, or islands) may take longer. You can check the estimated delivery date on the carrier’s website using the tracking number we provide.
How your vehicle is shipped?
Unless otherwise noted, the vehicles we offer are shipped crated or on a pallet and do not come assembled unless you’ve selected our assembly service. Assembly typically requires a few basic tools and mechanical knowledge. If you're not confident in your ability to safely assemble a high-speed off-road vehicle, we strongly recommend selecting professional assembly or having it assembled by a local mechanic.

What does 95% or 98% Assembly Mean? What do I need to assemble if shipped in crate?

For shipping safety, most vehicles cannot be fully assembled prior to delivery.

Minor assembly is required—this typically includes installing mirrors, connecting the battery, adjusting handlebars, and other small components. Before operation, please ensure all screws and fasteners are tightened, engine fluids are at proper levels, and the battery is fully charged. Your factory warranty remains valid right out of the box.
