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
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 65mph, 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 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 19hp (14kW) 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. Modified XR 250's were even raced in the GNCC's by Scott Summers. This bike was discontinued in 2004, replaced by the more modern CRF 250X.
XR 250L
This is the road legal version of the xr250r. the primary differences being on road lighting (head, tail, brake, and turn indicators). It also received D.O.T. (road legal) tires, metal fuel tank, key ignition/ steering lock, and many other small changes to make it more suitable for road use, this usually 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 bike entire was updated. The updated engine put out a usable 19hp (14kW) at 8100 rpm. Though the bike was new, it kept the antiquated air-cooling and conventional suspension fork. This bike 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 32hp (24kW) 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 2006, Honda replaced the XR 400 with the CRF 450X.

XR 600R
A 1993 Honda XR600R
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 at 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 38hp (28kW) at its peak (Kerker Dyno Dirt Rider Magazine Aug/1985, Kerker Dynos notoriously gave much lower HP readings than most other dyno's), but its torque was impressive @ 32 FT LBS. In 2000, Honda replaced this desert warrior with the XR 650R.
Early versions had a twin carburetor setup 85-87 later model (88 onwards) were designed to run on a single carburetor and coupled with a completely different bodywork styling took the XR to the next level. 85 and early 86 models were believed to suffer from 3rd gear problems when exposed to heavy use, this was addressed in later 86 and all 87 models. The late 86 model is regarded as the best to own from all the XR 600R models, it has the best color scheme, the best styling, 88 onwards were plain in comparison and lost the rugged appeal attained by its predecessor. The XR 600R make excellent super motocross conversions although difficult to achieve on the 85-86 due to the rear drum brake setup, this would require a bespoke back wheel to be fabricated as they are not commercially available for these models.
XR 650R
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 100mph (160km/h). The stock Australian geared bike can reach 180km/h.
