Honda XR series
Honda XR series
The Honda XR series motorcycles are a range of single cylinder four-stroke off-road motorcycles that were designed in Japan and assembled all over the world. The series is gradually being replaced by the similar CRF series. Some of the XR series came in two versions, R and L. The R version bikes were designed for off-road riding; they had very few creature comforts, and tended to come standard with knobby off-road tires fitted. The R version bikes, without modification, generally were not street legal. The L version bikes were designed to be street legal dual sport models, with appropriate lighting, tires and other features needed to ride on public roads.
In its heyday, the XR series consisted of 10 models; however, currently only the dual-sport XR 650L remains. The rest of the XR line has been transitioned into the CRF line, however the 50, 70, and 80 pretty much remain unchanged from their XR heritage.

Small XR models
The bikes that fall under this category are physically smaller than any of the other bikes in the series. They are predominantly designed for children, or as pit bikes, for recreational fun, nothing more. For an adult rider, they would not be comfortable for a ride of any length.
XR 50R
The XR 50 is a small 4-stroke 50cc child's entry level motorcycle. produced from 1968 until today originally called the Trail 50, then Z-50, the XR 50, CRF 50, and now a street legal (mini motard) version called the XR 50. This model is currently not sold in the United States due to the CPSIA.

XR 125L
The XR 125L was released the year 2004 and was discontinued in 2009, manufactured in just three colors, red, black and white the most common of these colours being red.
The 125 is a popular learner bike for many due to its highly forgiving handling, long-travel suspension for absorbing otherwise dangerous bumps, excellent fuel consumption (80-90mpg) and highly reliable four-stroke 124cc engine. While not a particularly powerful 125cc bike, generating 11.13 HP (8.1 kW) at 8500 RPM, and a top speed of around 65 mph, the engine is generally regarded as being, with adequate maintenance, all but bullet-proof when it comes to reliability. The XR 125L doesn't feature a kick start, but its dependable electric start and ease with which this bike can be bump-started negates the need for one.
Tires on this bike are generally dual-sport as standard, being grippy enough for road riding, but having a deeper tread than usual to allow for a little off-road riding without submitting to the on-road handling problems associated with full off-road knobbly tires.

XR 200R
A very popular trail bike. The XR200 is considerably lighter than the XR250 thus making it handle much better. The soft suspension makes it very comfortable for long travel or rough terrain. The XR200 stopped production in 2002. Pre 1993 models were built for more performance suspension wise. The 1984 and 1985 model years had RFVC 4 valve motors but had over heating problems due to lack of an oil cooler, most 84s and 85s motors have not survived.
XR 250R
For many years, the XR 250R was the standard small-bore off-road four stroke. It had a 249 cc air-cooled motor with Honda's famous Radial Four Valve Combustion Chamber (RFVC). In 1996, the bike was entirely updated. The updated engine put out a usable 19 hp (14 kW) at 8100 rpm. Though the bike was new, it kept the antiquated air-cooling and conventional suspension fork. The XR 250R was the king of entry level off road four strokes. It was simple, indestructible, and reliable. This bike was discontinued in 2004, replaced by the more modern CRF250X.
XR 250L
This is the street legal version of the XR250R. The primary differences between the two include on-road lighting (head, tail, brake, and turn indicators), D.O.T. (road legal) tires, metal fuel tank, keyed ignition/steering lock, and many other small changes to make it more suitable for road use. This comes at the expense of off road ability, and added weight (about 40 lbs). It also used a different carburetor and the exhaust headers were 3mm smaller than the R's to meet emissions requirements. It had a 249 cc air-cooled motor with Honda's famous Radial Four Valve Combustion Chamber (RFVC). In 1996, the entire bike was updated. The updated engine put out a usable 19 hp (14 kW) at 8100 rpm. Though the bike was new, it kept the antiquated air-cooling and conventional suspension fork. This motorcycle was discontinued in 2004.

XR 400R
Introduced in 1996, the XR 400R was wildly popular. It was reasonably light (264 pounds) and made a pleasant 32 hp (24 kW) at 7600 rpm. It shared a frame, plastic and suspension components with the XR 250R, and had a similar air-cooled engine with RFVC technology. XR 400's were heavily modified and raced. In 1998, however, Yamaha eclipsed the XR 400R with its answer to the mid-size off-road four stroke: the WR 400F. The WRF was much more advanced in technology than the XR. In 2004, Honda replaced the XR 400 with the CRF 450X.
XR 500R
Early twin shock model. Followed by a monoshock four valve XR 500. In 1983 motor was upgraded to RFVC technology with full cradle frame to suit. This won the Baja race and was quickly revised to 600 cc (see XR 600R). -Produced from 1979 through 1985

XR 600R
The XR 600R was king of the Baja races. It was introduced in 1985, and was updated again in 1992. The XR won many desert races in the hands of Johnny Campbell and Scott Summers. Its air cooled engine was very similar to the XR 400 and XR 250 engines, with the same RFVC valve train. The XR 600 only made 38 hp (28 kW) at its peak, but its torque was 32 ft·lb (43 N·m). In 2000, Honda replaced this desert warrior with the XR 650R. XR 600's were even raced in the GNCC's by Scott Summers
XR 650R
Introduced in 2000, the XR 650R was not just an update to the XR 600—it was a totally new bike. An all-new 649cc, liquid cooled, SOHC engine was mated to an aluminum box frame. The large XR did carry substantial girth, however, at 280 pounds dry.
The XR 650R is an incredible desert racer. It has won every professional desert race its entered. It remains one of the few stock dirt bikes that can touch 100 mph (160 km/h). The stock Australian geared bike can reach 180 km/h.
The 649cc SOHC motor of the XR pumps out an incredible amount of usable power. The stock unit turns 20.6 hp right off idle and maxes at 45.2 hp once the motor reached 6600 rpm. The power is spread evenly across the powerband without any major glitches or hiccups, although power does tail off well before it hits the 8400-rpm rev limiter. Many riders agree on the user-friendliness of the big 4-stroke and few are displeased with the performance of the engine.
XR 650L
The Honda XR650L is a street/trail bike that is more similar to the XR 600R than the XR 650R. It has a steel tube frame as opposed to an aluminum spar frame like in the XR 650R. It also has an air-cooled 644 cc SOHC dry-sump single cylinder 4-stroke engine similar except for an increased displacement to the XR 600R, unlike the totally redesigned XR 650R that has a liquid-cooled 649cc SOHC dry-sump single cylinder 4-stroke engine. With a headlight, taillight, turn signals, mirrors, smog system, revised exhaust system and a 2.8 gallon gas tank with 0.6 gal reserve, the 650L has a 349 lb (158 kg) wet weight.
