Kawasaki KZ750 LTD: Performance and Style

The Kawasaki KZ750 LTD, a motorcycle that straddles the line between utilitarian transport and stylish cruiser, offers a unique blend of performance and aesthetics. While its "LTD" designation might suggest a focus on show over go, the underlying KZ750 heritage hints at a more potent machine. This article delves into the intricacies of the KZ750 LTD, examining its engine, handling characteristics, comfort, and overall appeal to riders.

Engine and Performance

At the heart of the KZ750 LTD beats a 74 horsepower, dohc, inline Four engine. This powerplant features a bank of four 34mm Keihin CV carbs, a 66 by 54mm bore and stroke, and a 9:1 compression ratio. Kawasaki's transistorized electronic ignition ensures reliable starting, and the absence of a kickstarter contributes to a lighter overall weight. While the engine's core specifications remain largely unchanged from previous iterations, subtle modifications to cam profiles in earlier models aimed to address issues of low compression that could arise from missed shifts or over-revving. Kawasaki states these issues are now in the past.

The final drive gearing has seen a slight alteration on the LTD model, with the rear sprocket being one tooth smaller (32 teeth) to compensate for the reduced diameter of the rear tyre. However, the overall gearing remains remarkably similar between the standard and LTD versions, ensuring a comparable riding experience in terms of acceleration and top speed.

When ridden aggressively, the KZ750 LTD can certainly unleash its 74 horsepower. However, direct comparisons with its predecessors reveal a slight performance deficit. A previous Kawasaki 750 tested achieved a quarter-mile time of 12.26 seconds at 107.78 mph, making it the fastest 750 tested at the time. The LTD, in contrast, recorded a quarter-mile time of 12.62 seconds at 104.19 mph. This difference in terminal speed suggests a noticeable reduction in horsepower, potentially attributable to factors such as the engine's break-in period, the 18-inch tyre on the standard model, or even variations in tyre compounds. Despite this, the LTD retains Kawasaki's signature incredible mid-range punch, evident in its roll-on performance.

Even with these figures, a motorcycle completing the quarter-mile in the mid-twelves is far from slow. The LTD delivers a potent sensation when accelerating from a standstill, overtaking cars on the freeway, or pushing the speedometer to its limits. The engine's air suction emission system ensures clean exhaust emissions and contributes to its excellent running characteristics. It starts instantly, whether hot or cold, and can be ridden without the choke almost immediately. Throttle response is precise, and there's no hesitation during acceleration, even when the engine is cold. Vibration is present, though less pronounced than on some competitors like the Honda 750 Custom, but a rubber-mounted engine could further enhance rider comfort.

Handling and Suspension

The KZ750 LTD's handling is a complex interplay of its chassis, suspension, and tyre choices. It features Bridgestone Mag Mopus tyres, with a 3.25H-19 at the front and a larger 130/90-16 at the rear, both tubeless and adorned with raised white lettering. While a 16-inch rear tyre can sometimes compromise handling, Bridgestone's advancements have allowed the KZ750 LTD to remain a better-than-average handling machine even with the fatter rear tyre.

However, the suspension on the LTD is noticeably softer than on the standard KZ750. Rear spring rates are approximately nine-tenths as firm, but damping rates are significantly softer. Compression damping is halved, and even the adjustable rebound damping is considerably gentler. At its stiffest setting, the LTD's rear shocks offer rebound damping comparable to the softest setting on the standard model. Similarly, the fork spring and damping rates are also around nine-tenths as firm, though air pressure in the forks can provide some compensation.

These softer suspension settings, combined with frame geometry tweaks, aim to mellow the LTD's steering response. The LTD is equipped with leading axle forks, which alter the trail. To counteract this, the triple clamps have been revised. Furthermore, the steering rake has been increased to 30 degrees from the standard model's 27 degrees. With reduced offset on the triple clamps, the trail has increased from 4.2 inches to 4.8 inches. These changes are designed to slow down the steering, making it less twitchy than the standard KZ750, which can feel overly sensitive and prone to turning more sharply than intended. This added stability makes the LTD a more composed companion for commuting and open road riding, while still retaining enough agility for spirited cornering.

Despite the softer suspension and fatter rear tyre, the LTD is lauded as one of the best-handling semi-choppers in the 750 class. Compared to other "LTD" or custom variants with softer suspensions, the KZ750 LTD suffers less from a loss of cornering clearance. While it's possible to scrape pegs and even the centrestand or brake pedal under hard cornering, these instances require deliberate effort from the rider. The LTD maintains an above-average amount of cornering clearance, a testament to its well-engineered chassis.

Rider Comfort and Ergonomics

The rider's experience on the KZ750 LTD is a mixed bag, with comfort being a primary consideration. The plush suspension contributes significantly to a comfortable ride, managing to absorb road imperfections without excessive wallowing, even in high-speed sweepers. This is an impressive feat for a softer suspension setup, likely aided by the bike's relatively light weight.

However, the ergonomics present some challenges. The handlebars, while narrower than some competitors, feature a more pronounced rise on the LTD model, contributing to a tiller-like steering feel that can interfere with precise handling control. This, coupled with the laid-back riding position dictated by the handlebar and seat combination, can lead to backache for riders not accustomed to this posture. The two-piece seat, while aesthetically pleasing, offers less padding than the standard KZ750, making the ride feel firmer than the suspension might suggest. The pillion seat, however, is relatively flat and spacious enough for most passengers.

Other thoughtful touches enhance the rider experience, such as the non-glare rear-view mirrors and self-cancelling turn signals that can also be manually operated. These details set the LTD apart and contribute to its overall appeal.

Styling and Features

The styling of the KZ750 LTD is a significant departure from the standard model. It boasts a bright engine, short front and rear chromed fenders, and the distinctive two-piece stepped seat. The small teardrop tank, short mufflers, and revised gauges and headlight shell further contribute to its custom look. Compared to some other semi-choppers, the LTD leans more towards chrome and less black, exuding a more luxurious feel.

Kawasaki's success in styling the LTD will ultimately be judged by sales figures, but it is generally considered a mid-pack styling success, with both better and worse "luxo" models available in the market. The attention to detail in features like the mirrors and turn signals demonstrates a commitment to rider convenience and a desire to differentiate the LTD from its competitors.

Brakes and Fuel Economy

The braking system on the KZ750 LTD is generally good, requiring little pressure and offering sufficient power to lock a wheel if necessary. However, stopping distances recorded during testing were only average for the class. While comparable to the standard KZ750, they fell slightly short of the performance achieved by models like the Honda 750 Custom, which managed shorter stopping distances with the same tyres. The primary issue appears to be control, with the rear brake being prone to locking up too easily, making precise braking more challenging. If the full potential of the Kawasaki's brakes could be utilised without wheel lock-up, shorter stopping distances would likely be achievable.

In terms of fuel economy, the LTD performs admirably. The tested model returned 47 mpg, a couple of mpg better than the previous year's standard model. While this difference is slight and could be attributed to normal production variations, it is a welcome improvement. However, with a 3.25-gallon fuel tank, the LTD's range is somewhat limited. The vacuum-operated petcock typically switches to reserve after about 130 miles, with a low fuel warning light indicating when it's time to refuel. A larger fuel tank would undoubtedly enhance the practicality of the LTD for longer journeys.
