Yamaha DT250 Enduro: True to its trail-bike origins In keeping with its trail-bike heritage, the Yamaha DT250 brings with it the assurance of safe riding and excitement.
One of the most popular dual-sport bikes in the past the 250-cc wheeler was the answer to prayer for DT 125 riders.
It was elegant easy to use, simple and nostalgic which is a quality sought after in the current market.
The Yamaha DT250 was a dual-sport bike with an enduro design manufactured by Yamaha between 1971 and 1982.
It was a stylish motorcycle with minimal styling with a top speed of 85 mph and a YZ-specific Mono-cross suspension on the rear. It performed as well on the roads, just and on trails.
The service restrictions aside The Yamaha DT250 is a top choice for budget-conscious riders and fans of retro-styled motorcycles.
Discover all you can about DT250 and let this article inform you about its specifications and enticing features.
About Yamaha DT250
Similar to its sibling with a smaller displacement like its smaller-displacement sibling, the Yamaha DT250 is an ancestor of the 1968 DT-1 Enduro – the trailblazer which launched the off-roading two-wheeler segment for Yamaha.
The DT250 was the 9th-largest motorbike class of the DT series and was launched three years before the 125cc class that is its namesake.
It was released at the perfect time that was designed to be in line with the change of attention of consumers away towards off-road-worthy cars instead of road-legal vehicles.
As one would expect, it is expected that the DT 250 is not without rivals, and it’s in this regard that many fans have found Yamaha not quite up to scratch.
It could have been the ideal moment to invest all of your money on enhancements to the vehicle and reap the benefits of spending money on improvements.
The problem is that Yamaha seemed to have observed the situation differently. If it had done the same level of enhancement on the DT250 the way it did on the RD400 Yamaha, it would have violated the fundamentals that are the DT series.
Even though dual-purpose equipment should be competitive in its functionality, however, it should not be outside the purchasing capabilities of the average consumer.
In retrospect In hindsight, it appears that the Yamaha DT250 trod the path that was intended to be followed.
For all that, purpose-built wheelers typically progress slowly but steadily. In support of this assertion, Yamaha did introduce some significant improvements to the motorcycle that include The MX rear suspension reed valve torque induction, an electronic CDI system, as well as automatic oil injection.
While not spectacular they did improve both the performance overall and the aesthetic of the trail bike for street use.
Yamaha DT 250 Specs & Features Engine
A 2-stroke air-cooled single-cylinder engine with torque induction brings this Yamaha model to. It has a bore-stroke proportion of 70 x 64 millimetres (2.76 2.52 inches). 2.52 inches).
The engine displacement is 246 cubic centimetres (15.01 in3) while it has a compression ratio of 6.7:1. A Mikuni carburettor with a 28-mm diameter manages the mixture of air and fuel.
A plunger-type oil pump as well as an air filter made of foam that is oiled complete the bike’s powerplant setup.
The dirt bike’s engine setup results in the top speed of at least 68 mph (109 km/h) and a highest torque 17.5 Nm (1.78 kgf-m, 12.95 ft-lb) @ 6,500 RPM and 15.69 horsepower (11.7 kW) @ 5,400 RPM .
Before 1978, Yamaha DT250 models reportedly had the slight advantage of having a higher output of horsepower with 20 horsepower (14.91 kW) at 6,500 RPM.
There was also an increase of 26% in top speed, which was 85mph (137 km/h) when compared with older models.
(1977 Yamaha DT250F advertised figures: 23 horsepower @ 6,600 RPM and 27 Nm/2.8 kgf-m, 20.25 ft-lb @ 5,000 RPM)
Fuel & Lubrication
Its tank capacity stands at 9 Liters (2.38 US gal) of unleaded gasoline that has the minimum PON 87/RON91 rating. The fuel is transported via an elastomer and can provide an impressive fuel efficiency at 95 MPG (2.50 L/100 km).
For the highest efficiency, the bicycle needs fuel that contains less than 5percent in MTBE (Methyl Tertiary Butyl Ether) and 10 per cent ethanol, or less than five per cent Methanol.
However, some experts suggest steering away from fuels that contain Methanol due to their formaldehyde-rich level.
The engine’s oil capability of the engine is 1200 + 50 Cc (dry) and 1,100 + 50 ( oil change) of Yamalube SAE 10-W-40 2-stroke oil, or equivalent. For compatible versions, the API minimum grade is SJ and must meet JASO standard T903 MA.
You may opt for other manufacturer-recommended viscosity grades, depending on ambient temperature. If you are unsure you are not sure, consult the service manual for more details regarding oil specifications.
A manual, five-speed drum-shifter that is constant mesh and a wet multi-disc clutch assembly supply electricity to the floor.
A Daido roller chain (with 104 links, including joints) is used to control wheel spin. This dirtbike’s transmission with a wide ratio allows it to be comparable to similar models such as the Harley-Davidson SX250, Team Green’s KE250B as well as the Honda XL250 just to mention a few.
To increase acceleration, it is possible to modify the front sprocket to 1 or 2 teeth lower.
To help you, the standard gear ratios are as follows:
|Primary Reduction Ratio||2.826 (65/23)|
|Secondary Reduction Ratio||3.357 (47/14)|
|Transmission Gear Ratio (1st)||2.538 (33/13)|
|Transmission Gear Ratio (2nd)||1.789 (34/19)|
|Transmission Gear Ratio (3rd)||1.300 (26/20)|
|Transmission Gear Ratio (4th)||1.000 (23/23)|
|Transmission Gear Ratio (5th)||0.769 (20/26)|
Contact breaker point ignition system as well as a primary kick-starter to wake it up for the DT250.
In contrast to the electronic ignition systems (which is typical for dirt bikes with DT250 models), it is the ECU that switches the first’s primary circuit either off or on.
It also runs with lower voltage, and it transfers the same voltage for the coil as well as wiring systems. It took nearly six years for Yamaha to convert the breaker-point ignition to the CDI system.
This includes the 1998 Yamaha DT250, all pre-1980 models require the NGK B8ES Spark Plug that has an opening of 0.7 to 0.8 millimetres (0.028 to 0.031 millimetres).
In terms of battery requirements, The models were divided into two categories. 1974-75 Yamaha DT250s were equipped with 4Ah/(10 HR) 6N4B-2A-3 battery types (view at Amazon) in contrast from 1976 to 1979, DT 250s were equipped with 6Ah/(10 HR) 6N6-3B-1 batteries.
They differ in size and amperage, and aren’t interchangeable. The 6N4B-2A-3 format measures 48 x 96 mm (4.00 x 1.88 3.75 inches) 3.75 inches) and the 6N4B-2A-3 format measures 99 5 x 111 millimeters (3.88 x 2.25 4 .38 millimeters).
Tires & Brakes
E-type aluminium wheels come with Dunlop(r) 3.00 21/4PR for the front tire and 4.00 18 4PR rear tires.
This wheel-and-tire assembly connects to drum brakes that expand 160-/150-mm and supply the stopping power of the DT250.
If the tires are damaged or worn, change the original rubber with Shinko 700 Dual Sport Front Tires (view on Amazon).
For more serious mudding or challenging tracks, you can change the rear tires to Dunlop D605 Dual Sport Tires (view on Amazon).
The recommended tire pressure depends on the speed of the rider and their weight. For normal use cold tire pressure must have 127.5 kg (1.3 kg/cm2, 18.5 psi – front) and 147 KPa (1.5 kg/cm2 21 psi back).
If you are riding at high speed or with the assistance of a passenger the tires should have the 147-kPa (1.5 kg/cm2, 21, PSI) as well as 176.5 kPa (1.8 kg/cm2, 25.6 psi) at the front and back respectively.
The long-travel suspension is comprised of an oil-damped telescopic fork in front with an axle mounted forward.
In the rear, there is a mono-cross swingarm that is DeCarbon-style which is part of the YZ range.
Each configuration offers 195 mm (7.6 inches) 140 millimetres (5.5 inches) of wheel travel and 140 mm (5.5 inches) of wheel travel.
A nitrogen-charged mono-shock that has softer spring rates complements the cantilever on the back.
The suspension system in all its components contributes to the DT250’s excellent handling, good cornering, and better performance on rough surfaces.
Dimensions & Capacities
The overall dimensions of the vehicle are 2,185 x 870 x 1165 millimetres (86 x 34.3 3.43 x 45.9 inches, L W x H) It is exactly like its larger sibling and it’s the Yamaha DT400D.
The later-year versions also had the same measurements, but with minor improvements to the length of the wheelbase (from 55.7 up to 55.9 inches).
The saddle is 856 millimetres (33.7 inches) high, and the clearance to the ground isn’t as good at 255 millimetres (10 inches).
The minimum clearance was later increased to 277 millimetres (10.9 inches) for subsequent models.
The bike’s wet and dry mass steadily increased from its initial production model. From 129 kilograms (284 pounds.) in 1974, the DT250 was able to add 6 (6) pounds to curb weight.
Modifying the fuel tank and removing a little from the capacity of fuel helped cut the weight of wet for models made post-77 to 131 kg (289 pounds. ).
A skid plate of aluminium shields the crankcase from damage and gnarls. Turn signals are secured to the front and are the rubber mounts are secured in the rear.
The footpegs that fold are serrated and 13 inches tall, allowing for a more relaxed but more aggressive riding posture.
Round headlights complete the classic DT250 look that is characteristic of its time.
As we’ve already mentioned, one of Yamaha’s most appealing appeals is its nostalgic vintage style.
It is proud of its 1970s-inspired look and has two pieces, such as the brake levers and instrumentation and a duplex frame.
It received minimal to none of the cosmetic changes during its time. A redesign of its seat and tank make up the bulk of the bike’s visual improvements.
Despite this, however, even with this flaw, the DT250 is highly regarded for its convenience and weight distribution.
This is for the two-wheeler as it’s weighty for a dirt 250 class bike.
There are plenty of options available which will allow any owner to take some weight off the bike’s trail and stop it from appearing too old-fashioned.

- There’s a small delay in the engagement time when you squeeze the lever for the front brakes. However, many have reported that an ’81 YZ250 backplate that has two levers pressing on the brake shoes in two different places solves the issue. Naturally, it is far better to use front disc brakes.
In contrast to the current dual-sport models unlike the current dual-sport machines, the DT250 is specifically designed to be used 70% off-road, and 30 per cent on-road.
