Review Yamaha BT 1100 Bulldog

species protection

To ensure the continued existence of the Bulldog, had to Yamaha lifted the air-cooled V-two-cylinder, which had already powered the TR1 at the beginning of the 80s and gave wings to the XV 1100 chopper, to the Euro 2 standard. That is why the two-in-one-in-two exhaust system now accommodates two catalytic converters connected in series. A solenoid valve in the carburetor interrupts the fuel supply when overrun so that the catalytic converters are not damaged. Redesigned carburetor covers and "baffles" for air supply are intended to reduce the temperature of the rear cylinder. For this reason, the housing of the secondary air system also had to be relocated.
Lots of measures so that
but have no effect on the performance or characteristics of the low-speed two-cylinder. The engine pushes forwards vigorously and smoothly just a little above idle speed, builds up a considerable torque peak at moderate speeds and demands the next higher gear beyond 5500 tours.
The changes to the chassis, more precisely to the front double disc brake, are just as inconspicuous. The perforated brake discs come from the Road Star Warrior, the one-room brake calipers from the R6 (previously R1) and the main brake cylinder (15 millimeter piston diameter) from the XJR 1300. All in all, a perfectly working, easy to dose brake that can be used with little manual force. Actually as before.
However, there are modifications that are immediately noticeable. For example the subtle two-tone paint or the matt black, which runs through the frame and the swing arm to the gimbal housing. Or the electronic immobilizer. And the cockpit, which, in addition to a changed arrangement of the speedometer and rev counter, now has a multifunctional display. Unfortunately, a fuel gauge is missing (still only a control light) and the
Instruments are difficult to read because of their finer scale.
In any case, the pillion seat has become better because the passenger no longer constantly slides in the driver’s back, but can sit comfortably where he belongs. For the driver, however, nothing has changed. Despite the new handlebar, the ergonomics have remained the same. Like all new motorcycles, the Bulldog now has permanent driving lights and hazard warning lights. And like all Bulldogs, the current model also impresses with its good-natured driving characteristics. The rear suspension could be more sensitive, but a narrower rear tire could make tracking easier. But that doesn’t seem to jeopardize the survival of the species. nk
