Gold-painted 19-inch wheels were mounted front and rear, as well as a chain drive and a pair of tracker-grade Maxxis DTR1 medium tires. At the rear, two 350mm YSS adjustable shock absorbers have been added to better fit the new forks, and a Saddlemen Eliminator seat unit has been modified to fit. “It starts and works every time and has been driven off the road onto a dirt road. And then I went home. Keeping this battery plugged into a charger is a small price to pay to be able to drive this tracker on the road. “It`s titled and legitimately legal on the street,” Brad says. “Which is not easy to achieve in my condition. Some details may be relegated to gray areas. Finding one today can be a difficult and expensive task. If you do, all you have to do is add lights and a license plate. If you`re extremely lucky, you might find one of the few KR series motorcycles homologated for the road. If you do some research, you may find that your condition allows you to jump the turn signals for a vintage bike, but you need to refresh your hand signals.
Why not start with the great-grandfather of the modern tracker genre? The Harley-Davidson KR750 dominated the AMA Grand National series for decades. Many might point out that the rules favored flathead engines. The H-D KR750 had a V-twin engine with a displacement of 741.68 cc and was specially designed for flat track racing. H-D built the KR750 between 1952 and 1969, when better street bikes were available, but AMA rules did not allow them on the track. Harley tried again for the 2009 model year by introducing the XR1200 to the North American market. The XR1200 has more of a street-following look, with the sleek tank flowing easily through the tank and rear wing and taillight. It`s powered by H-D`s EVO 1200 engine – rated at 90hp in this configuration – and can be quickly modified to achieve a complete road-following look. With a little research online, you should be able to find a kit that will help you get the job done in just one day. After the scrapping of the KR, Harley went straight into production of the XR750 for the 1970 race year.
Between 1972 and 2008, XR750 riders won 29 AMA National Championships. The XR750 was also the favorite bike of legendary stuntman Evel Knievel. The XR750 and its street racing twin, the XRTT750, feature an air-cooled 748cc V-twin with two 36mm Mikuni carburetors. All beautiful constructions, but too much Harley. My last object of desire is a street tracker based on the Yamaha Mt 07. The modern motorcycle has many iterations: Bobber, Café Racer, Dual Sport, Cruiser, Dirt Bike, Chopper, etc. But perhaps one of the funniest things to drive is the route tracker. A street tracker offers the naked appearance of a flat track runner and always has the equipment you need to get street approval. These bikes have wide handlebars on the riser, good low-end performance, and most have fiberglass hedges, chain drives, and equally sized front and rear wheels (usually 19″). They`re patchy on the street, fun in the dirt, and brimming with history.
We understand that there are many other bikes that can be converted into a road tracker. We`ve seen everything from Honda Goldwing Street Trackers to full-fledged “cameramen” built around custom frames like this Triumph 650, based on a Redmax C&J frame replica, or the Fuller Moto Ducati Street Trackers. The Harley-Davidson XR750 is undoubtedly one of the most successful motorcycles in the recent history of American flat track racing. Originally introduced in 1970 as a modified Sportster, after a major overhaul in 1972, it evolved into a conquering flat tracker and then dominated the AMA Pro Flat Track Grand National Championship (GNC) for most of the last four decades. We own a 1989 XLH1200 Sportster — “Flash Tracker”. Although the bike is not designed as a traditional route tracker, it has several tracker design tips. We offer and recommend the robust Stiletto Shocks (15″), Scrambler Bars and Bates Baja from W&W Cycles. This is a Harley-Davidson Sportster 1200 Street Tracker, a custom motorcycle inspired in equal parts by the classic Harley XR750 Flat Tracker and the influential construction catalog of the British Charlie Stockwell. However, shutdown is not a problem; This tracker has a front brake.
The calipers are Brembo, but Lyndall supplied the iron brake discs – 320mm at the front and 10.5 inches at the rear. The front semi-trailer is custom made and there is an A&A Racing rear bar with quick-change rotor and sprocket holders. The rear master cylinder is Grimeca. Discreet LED lighting at the front and rear makes this XR750 road legal. It`s a bare electrical system with a total loss, but it works. “I can easily run a dozen fuel tanks over battery life,” says Brad. “I use BBRP (Brian Billings Racing Products) to run this XR,” says Brad. “It has tuned a lot to make it a reliable road bike: it works perfectly and is not grumpy or capricious.” This could explain why the spec sheet of this XR750 is pure gold street tracker. The engine is powered by two Sudco Mikuni TM 38 flat slides that breathe through Darcy racing inputs. Bill Werner Racing supplied the exhaust silencers and SuperTrapp as well as the wet clutch. This is especially true for the XR600R, the famous desert race car of the 1990s, which was primarily sold as a pure off-road model.
It will most likely have to be converted into a street bike. This is easier to do in some states and countries than in others. With that in mind, let`s first take a look at some of the purest forms of the flat tracker that serve as prototypes for the trackers to come. There`s that old adage from the auto industry: “Win on Sunday, sell on Monday. Soon, the riders wanted to put their track bikes on the road. To achieve this, they had to modify their flat trackers so that they were legal on the street. It was pretty simple: just add lights, mirrors, a horn and front brakes. Track bikes had to be quick starts back then, so kick starts were a nice bonus. There are currently no immediate plans to introduce a road-legal version of the XG750R. If we ever run out of ideas and succumb to EXIF, you can guarantee that the Harley-Davidson XR750 Flat Tracker will be included in our list. And we were complaining that there was never a road approval. Road trackers were originally designed to allow people to drive their flat track riders on the road, things like headlights, turn signals, front brakes, and license plates are added to make them legal on the road while keeping the minimalist nature of the flat tracker as intact as possible.
Omar also sells a 19-inch rear wheel conversion kit, fork protectors, front license plates and various other XS650 road tracking accessories. One of our favorite XS650 versions inspired by the flat track is Ride and Sons` Oval 79, pictured below: It`s hard to choose a Sportster that might be a better fit for a road-tracking project. They are all easily adapted to the genre. Pre-1991 Sportsters already have chain drives – meaning a chain conversion kit is not required – although they do have four-speed gearboxes instead of later 5-speed gearboxes. By far the most popular motorcycle as a donor for a road tracking project is the Yamaha XS650. Several thousand of these bikes were built between 1968 and 1979. That means a lot of donor bikes that should be pretty inexpensive. This also means that there are many spare parts. The task of converting this legal road unit into a premium flat track race car was taken over by Vance & Hines Motorsports, resulting in the XG750R, which will make its racing debut on May 29 at Springfield Mile in Illinois, USA.
