Overview and Background

Yamaha first introduced the DT400 in 1975 and it quickly earned a reputation as a rugged, entry-level enduro bike.

On And Off-Road Handling Performance

The DT400 finds the sweet spot between rugged dirt competence and road-going manners. Its compact, mild-mannered 399cc engine puts out smooth, tractable power perfect for navigating tight singletrack or unpaved backroads.

With a mellow powerband focused under 7000 rpm, it’s beginner-friendly and suited for technical riding. There’s still adequate grunt for highway cruising, it just needs more gear changes to hold higher speeds. The slick 5-speed transmission meshes cleanly with little clunkiness.

On the twisty stuff, the DT400 flickers side-to-side with ease thanks to its narrow profile and light feel. The non-adjustable 37.2 inch seat height clears the ground effectively for shorter riders, while not being too lofty for inseam-challenged pilots. Moreover, the comfortable seat and upright posture reduce fatigue over long days riding.

While it gives up ultimate agility to a pure MX bike, the DT400’s balanced geometry and compliant suspension instill confidence pushing harder on rough trails. The lower-specced spring components represent the DT400’s main limitation during aggressive off-roading. Braking performance from the single disc front and rear slows the bike reliably, if not exceptionally.

Overall, the DT400 delivers rock-solid handling for general trail exploration, just without the razor sharpness demanded by expert riders. It’s built for durability over maximizing either on-road or off-road prowess exclusively.

Beginner And Intermediate Riders

With its moderate power, compliant suspension, and low seat height, the DT400 serves up an ideal confidence-building platform for casual and less experienced riders. Novices can easily manage the smooth torque curve while learning how to balance and handle a full-sized motorcycle. Its tractor-like pull simplifies clutch work and maintaining momentum in technical sections.

The forgiving chassis also encourages new riders to explore limits and improve skills. Meanwhile its highway capabilities give you the option to expand your adventures. Overall the DT400 presents a versatile, unintimidating all-around motorcycle to grow with.

Expert And Aggressive Riders

In contrast, hard-charging veterans will notice the DT400’s off-road limitations, especially in rough and fast conditions. With a curb weight around 290 pounds, it’s on the heavy side for a serious dirt bike. And the budget suspension components cap how hard you can push before losing composure.

Savage singletrack and big air jumps are better left to pure MX or enduro models. Expert riders will yearn for sharper handling, stronger overall performance, plus additions like hand guards and skid plates. So while the DT400 can still thrill, its sweet spot remains mellower trail and adventure riding.

Yamaha DT400 Price – MSRP And Used Value

Considering its quality parts like the inverted fork and 6-speed transmission, the DT400 represents a tremendous value at an MSRP of $6,799. As a proven design with decades of R&D behind it, Yamaha can produce this bike very cost effectively. There’s no need to recoup extensive development costs like on a cutting edge sport bike.

The DT400 holds its value fairly well on the used market too. You can find clean secondhand models from the 2000s for around $4,000 give or take. And buying just a few years old saves substantially more. Of course condition, mileage, and included accessories impact pricing. But overall the DT400 makes a very enticing and affordable entry point into full-sized dual sport riding.

Here’s a quick snapshot of new vs used pricing:

  • New 2023 MSRP: $6,799
  • Used 2015 DT400: ~$4,000
  • Used 2020 DT400: ~$5,500

Next let’s walk through the standout strengths and compromises inherent in the DT400 value proposition.

Pros and Cons of the Yamaha DT400

DT400 Pros

  • Proven Reliability: With four decades of refinement, the DT400’s 397cc air-cooled thumper has proven itself over millions of miles of abuse. The pushrod engine layout eschews frills for slick reliability. And the electric start backed by a kick starter provides redundancy. You can trust this machine to carry you home.
  • Low Cost of Ownership: Thanks to its stone-age engine design and abundant spare parts supply, the DT400 costs very little to run and maintain. You can tackle most routine service in your garage and fix roadside problems with basic tools. It also sips gas, achieving 60+ mpg in mixed riding.
  • Balanced Power Delivery: The mild-mannered motor provides smooth, predictable power without frightening new riders. It offers just enough grunt for highway cruising without making trails intimidating. Novices can build skills easily on this friendly package.
  • Excellent Value Retention: The DT400’s legendary reputation ensures strong demand for both new and used models. This keeps resale values high if you ever want to sell. Plus you get proven Yamaha quality for thousands less than over-specced models. The DT400 gives you the most bang for your buck.
  • Comfortable, All-Day Ergonomics: The comfortably padded seat, relaxed foot pegs, and natural handlebar bend reduce fatigue for long days in the saddle. And the low seat height suits both new riders and inseam-challenged veterans. You can rack up trail miles without abusing your body.

DT400 Cons

  • Heavy for Extreme Off-Roading: With a wet weight around 290 pounds, the DT400 verges on portly versus high-end dirt bikes. You feel the mass muscling through deep ruts and technical sections. This limits its agility for tough terrain compared to lighter MX racers.
  • Budget Suspension Components: While the adjustable fork and shock offer good compliance, the lower-grade spring and damping components compromise high-speed handling. Expert riders will notice the limited bump absorbency and chassis control when riding aggressively over rough ground.
  • Minimal Rider Aids: The cost-conscious DT400 eschews today’s high-tech rider aids like traction control, ABS, or GPS. You have to rely on old-fashioned rider skill. An old-school experience has appeal, but modern amenities do enhance safety and convenience.
  • Taller Riders Want More Legroom: The lofty 37 inch seat and low foot pegs are great for shorter riders, but cramp the knees of taller folks. If you’re over 6 feet tall, you’ll wish for more legroom when standing.
  • Price Creeps Up with Accessories: While the base MSRP seems very reasonable, you’ll likely want to add protection and luggage options. High-quality skidplates, crash bars, and pannier racks can quickly add $1,000+ to the out-the-door cost. Plan your budget accordingly.

Ideal Uses For The Yamaha DT400

The greatest benefit of the DT400 lies in its versatility as an affordable, low-fuss dual sport. While it lacks standout excellence in any one area, it delivers rock-solid competence across a wide range of riding purposes from enduro to adventure. Here are some of its best-suited applications:

All-Around Trail Bike

From wide-open fire roads to tight singletrack, the DT400 handles it all with competence. With the right tires and gearing, it adapts well to different conditions. No terrain will be truly out of its element even if you push the limits of its capabilities.

The common theme is that the DT400 presents an accessible, economical entry point into the middleweight dual sport category. Riders seeking more hardcore performance may want a KTM 500 EXC or Husqvarna FE 450. But it’s hard to beat the DT400’s blend of quality, reliability, and value.
