The Yamaha XJ 600 is a motorcycle model of the Japanese motorcycle manufacturer Yamaha from the XJ series.
She's a super athlete / sportsman with half shell 1984-1990 ( XJ 600)
Through both sporting properties as well as large practicality and because of the low price, this bike is spread still numerous today. Especially the good controllability makes it an ideal motorcycle for driving schools and learner drivers.
General
The XJ 600 was built over the years in various model series. The first series includes the XJ 600 51J with an output of 73 hp in the unrestricted version. In Switzerland, only a throttled model was sold with 34.9 kW to meet the local noise and emission regulations. As of 1989, the 3KM (73 hp) and 3KN ( 1) has been sold to all countries outside of Germany and Sweden. In Germany and Sweden, the modified XJ 600 came as 3KN ( 2) in the trade. Here, the electronics were modified and reduced performance due to the change in the statutory noise requirements to 66 hp. This not a new name in the frame numbering was assigned due to the limited supply. All XJ 600 of the first series starting with " 51J " and are to be distinguished from each other only on the basis of the following six -digit serial number. The factory- produced variant with 37 kW (50 PS) given the additional designation 51H.
Weaknesses
Typical weaknesses has the whole XJ series is not actually, as their is a sophisticated and uncomplicated technology based. Both XJ 600 at best you can say of a certain inclination to the handlebar flutter. As a rule, however, will only notice this if, for example tires were " square" driven by inattention while air pressure or when was sloppy when installing the steering head bearing. Also an error when installing the rocker or not exactly flush built rear impacts in this way.
The carburetor should be synchronized from time to time and also the valve clearance checked regularly, because negligence of the user this can sometimes quite significantly much fuel in the air. Who is technically not very talented person can thereby manage themselves.
Opportunities for improvement
As with all " bread and butter " machines can optimize the initial suspension properties.
1 suspension
The suspension of the old series is almost better than the new series. This is due to the different concepts.
The 51J was to be a super athlete to the drawing board. However, it was seen more as an athlete / sport touring and buy accordingly. Unlike many other motorcycles of the 80's, the chassis of the 51J in harmony with the engine performance. However, the landing gear is second choice by today's standards.
It is recommended to produce the conversion to progressive fork springs. Thus, the response is not only direct, which makes for more feedback from the road surface to the driver, prevents in connection with the conversion to tougher fork oil ( 15s instead of 10s viscosity) a breakdown of the fork it.
The strut can also be exchanged for higher-quality accessories, but mostly here is the improvement in the behavior not the very high cost (about 500 euros ) worth.
Second brake system
The front two-piston brake double the 51J is not only sufficient size, but also provides an even by today's standards for good braking performance.
As a weak point of your brake system and the rubber lines are often seen. These ensure, as with all cars and motorcycles with rubber brake lines, for a softer pressure point, which can be improved by upgrading to stainless steel brake lines.
3 tires
The factory tires and tire accessories later ( such as Michelin Macadam ) are now no more than timely. Significant advances in tire development are given clues many users through the following conversions:
The first election under the tire is for most XJ- driver of the BT 45 " Battlax " Bridgestone dar. Two mixtures, hard in the middle, soft on the flanks, reached the manufacturer for a high performance, 8000-15000 kilometers, on the other hand already builds the tires even at low operating temperature high adhesive forces, even when wet. If you keep constant the prescribed air pressure, it also reduces the latent tendency to link flapping all XJ -600 models.
Other alternative is the LaserTec Metzeler. The ride quality on average not quite reach the values of the BT 45, but he is also seen as a total USEFULLY tires.
