Honda XR series 806129 222176285 2008-06-27T22:52:03Z 207.53.193.109 /* XR100R */ [[Image:1980 restored xr200.jpg|right|thumb|1980 XR200]] The '''Honda XR''' series motorcycle is a range of single cylinder [[Four-stroke cycle|Four-Stroke]] off-road motorcycles that were designed in Japan and assembled all over the world. This series of motorcycle is gradually being replaced with similar [[Honda CRF series|CRF series]] motorcycles. Some of the XR Series motorbikes came in two versions, '''R''' or '''L'''. Simply, the R version bikes were designed with off road in mind; they had very few creature comforts, and tended to come standard with knobbly off-road tyres fitted. The R version bikes, without modification, generally were not street legal. Conversely, the L version bikes were designed to be ridden predominantly on road, with appropriate lighting, tyres and other features pertaining to road riding. In its heyday, the XR series consisted of 10 models; however, currently only the XR50,XR80 and the baja-racer XR650R and dual-sport XR650L remain. <ref>[http://powersports.honda.com/motorcycles/off-road/ Honda Off-Road Motorcycles - Review, Performance, Specs<!-- Bot generated title -->]</ref> The rest of the XR line has been transitioned into the CRF line. == The Small XRs == 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. ==== XR50R ==== The XR50 is a small 4-stroke 50cc children's entry level motorcycle. produced from 1968 until today originally called the Trail 50, then Z-50, the XR50, CRF50, and now a street (mini motard) legal version called the XR50.. again. ==== XR70R ==== ENGINE: <br> ENGINE 72cc, air cooled, single cylinder, four stroke, SOHC, two-valve <br> DISPLACEMENT 72cc.

While not a particularly powerful 125cc bike, generating 11.13 HP (8.1 kW) at 8500 RPM,<ref>[http://www.honda.co.uk/motorcycles/DispatcherServlet?hidAction=Lookup&hidActionDetail=viewproductspec&hidMSGID=11&hidMSGCode=CC125&hidMSGName=125+CC&hidProductID=63&hidSelectedProductCode=XR125L&hidProductName=XR125L#focusHere Honda Motorcycles Models<!-- Bot generated title -->]</ref> 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 XR125L doesn't feature a [[kick start]], but its dependable [[Automobile self starter|electric start]] and ease with which this bike can be [[Push start|bump-started]] negates the need for one. Tyres 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 tyres. == XR250R == [[Image:2004 Honda XR 250R.jpg|right|thumb|2004 XR250R]] For many years, this bike 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). <ref> http://www.motorcycle.com/mo/mcdirt/mcphotos/xr11.gif </ref> In 1996, the bike entire was updated. The updated engine put out a usable {{Convert|19|hp|kW|0|abbr=on}} at 8100 rpm. Though the bike was new, it kept the antiquated air-cooling and conventional suspension fork. <ref>[http://www.motorcycle-usa.com/Article_Page.aspx?ArticleID=481&Page=3 2004 XR250 vs DR-Z250 vs KLX300R - MotorcycleUSA.com<!-- Bot generated title -->]</ref> The XR250R was the king of entry level off road four strokes. It was simple, indestructible, and reliable. Modified XR250's were even raced in the GNCC's by Scott Summers. This bike was discontinued in 2004, replaced by the more modern CRF250X. == XR350R == Introduced introduced in 1983, Sold from 1983-1987.<br> Make Model: Honda XR 350R.

It was reasonably light (264 pounds) and made a pleasant {{Convert|32|hp|kW|0|abbr=on}} at 7600 rpm. It shared a frame, plastic and suspension components with the XR250R, and had a similar air-cooled engine with RFVC technology. XR400's were heavily modified and raced. In 1998, however, Yamaha eclipsed the XR400R with its answer to the midsize off-road four stroke: the WR400F. The WRF was much more advanced in technology than the XR. In 2006, Honda replaced the XR400 with the CRF450X. Specs<br> ENGINE Air-cooled dry-sump single-cylinder four-stroke, SOHC; four-valve RFVC <br> DISPLACEMENT: 397cc.

It was introduced in 1985, <ref>[http://www.dirtrodders.com/xr650r/bajaking.html Honda XR650R: The King of Baja<!-- Bot generated title -->]</ref> and was updated again in 1992. The XR won many desert races at the hands of Johnny Campbell and Scott Summers. It's air cooled engine was very similar to the XR400 and XR250 engines, with the same RFVC valve train. The XR600 only made {{Convert|38|hp|kW|0|abbr=on}} at its peak, but its torque was impressive. In 2000, Honda replaced this desert warrior with the XR650R. == XR650R == The XR650R was not just an update to the XR600--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. <ref> "Race Test: Honda XR650R."

It has a steel tube frame as opposed to an aluminum spar frame like in the XR650R. It also has an air-cooled 644 cc SOHC dry-sump single cylinder 4-stroke engine similar except for an increased displacement to the XR600R, unlike the totally redesigned XR650R 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 is a hefty 324 lb (dry weight). It is commonly referred to as the BRP(Big Red Pig). == See also == *[[Honda CRF series]] *[[Yamaha WRF series]] ==References== {{Reflist}} ==External links== *[http://powersports.honda.com/motorcycles/off-road/ Honda's off-road motorbikes] *[http://www.offroadvietnam.com/Images/motorbikes/hondaxr250.jpg XR 1999 model in Vietnam] {{Honda}} [[Category:Honda motorcycles|XR series]] [[nl:Honda XR]]
