Design and Features

The Honda CB650 and CBR650 motorcycles share the same 649cc parallel-twin engine, but their differences in design and features set them apart in terms of performance. The CB650 is designed for comfort and ease of use, while the CBR650 is geared towards sporty riding.

The CB650’s engine produces 64 horsepower at 8,500 rpm and 47 lb-ft of torque at 6,250 rpm. It features a slip-and-assist clutch that helps to reduce lever effort, making it easier for new riders to shift gears smoothly. The CBR650, on the other hand, puts out 67 horsepower at 9,000 rpm and 48 lb-ft of torque at 6,500 rpm.

The CBR650’s engine is tuned for better acceleration and responsiveness, with a more aggressive camshaft profile and higher compression ratio. This results in quicker throttle response and a more engaging ride experience. In contrast, the CB650’s engine prioritizes low-end torque and smooth power delivery for relaxed cruising.

  • Key differences:
    • Horsepower: CBR650 (67) vs. CB650 (64)
    • Torque: CBR650 (48 lb-ft) vs. CB650 (47 lb-ft) + Compression ratio: CBR650 (12.0:1) vs. CB650 (11.5:1)
    • Camshaft profile: CBR650 (more aggressive) vs. CB650 (softer)
  • Key similarities:
    • Engine displacement: 649cc
    • Number of cylinders: 2
    • Fuel injection system: Both use PGM-FI with two spark plugs per cylinder

Engine Performance

The Honda CB650 and CBR650 motorcycles share many similarities when it comes to their engine performance, but there are some key differences that set them apart. The CB650 is powered by a 649cc liquid-cooled parallel-twin engine, producing 64 horsepower at 8,000 rpm and 49 lb-ft of torque at 6,500 rpm. In contrast, the CBR650R features a 649cc liquid-cooled DOHC inline-four engine, generating 68 horsepower at 12,000 rpm and 47 lb-ft of torque at 8,500 rpm.

The increased horsepower and torque output of the CBR650R’s engine is noticeable when accelerating from a standstill. The bike quickly surges forward, feeling more aggressive and responsive than its CB650 counterpart. However, this extra power comes at the cost of a slightly rougher idle and a more pronounced vibration through the handlebars at higher revs.

In terms of acceleration, both bikes are relatively quick off the line, but the CBR650R’s lighter weight and more powerful engine give it a noticeable edge in this regard. The CB650, on the other hand, feels more laid-back and relaxed, with a smoother power delivery that makes it easier to manage in heavy traffic or slow-speed situations.

These differences in engine performance have a significant impact on the riding characteristics of each bike. The CBR650R is better suited for sporty riding and aggressive cornering, while the CB650 is more geared towards casual cruising and commuting. Ultimately, the choice between these two bikes will depend on the rider’s preferences and riding style.

Handling and Suspension

The Honda CB650 and CBR650 motorcycles differ significantly in their suspension systems, which has a profound impact on their cornering ability and overall stability.

The CB650 features a telescopic fork at the front, while the CBR650 sports an inverted fork. This design choice affects the bike’s steering response and feedback. The CBR650’s inverted fork allows for a more direct connection between the rider’s inputs and the road, resulting in enhanced handling and agility. In contrast, the CB650’s telescopic fork can feel slightly more vague, particularly at high speeds.

In terms of rear suspension, both bikes utilize a monoshock system, but with distinct design approaches. The CB650 features a traditional horizontal shock absorber, while the CBR650 boasts a more modern horizontal-back-link setup. This design choice affects the bike’s braking stability and cornering ability. The CBR650’s design allows for improved weight distribution during hard braking, resulting in enhanced stability.

Riding both bikes reveals significant differences in their suspension systems. The CBR650 provides a more responsive and agile feel, while the CB650 can feel slightly less refined, particularly during aggressive cornering. However, the CB650’s softer suspension settings do provide a more comfortable ride for everyday commuting.

Ultimately, the choice between these two bikes depends on your riding style and preferences. If you prioritize handling agility and precision, the CBR650 may be the better choice. However, if you prefer a more relaxed, comfort-oriented ride, the CB650 could be a better fit.

Riding Position and Ergonomics

The Honda CB650 and CBR650 motorcycles boast distinct riding positions, designed to cater to varying rider preferences and sizes. The CB650’s seat height measures 814mm (32.1 inches), while the CBR650’s seat height is slightly lower at 783mm (30.8 inches). This disparity may seem insignificant, but it can make a substantial difference for riders with shorter or taller stature.

The CB650’s handlebars are positioned at a more upright angle, which provides greater visibility and comfort during long rides. The CBR650’s handlebars, on the other hand, are slightly lower and more forward-slung, encouraging a more aggressive riding position. This design element may appeal to sport-oriented riders seeking a more dynamic feel.

The footpeg positions also differ between the two models. The CB650’s footpegs are situated higher up, allowing for greater leg extension during cornering or braking. Conversely, the CBR650’s footpegs are lower and more rearward-mounted, which can improve ground clearance during tight maneuvers.

In terms of ergonomics, the CB650’s riding position feels more relaxed, while the CBR650’s setup is more aggressive and sport-oriented. The CBR650’s seat shape and foam density are designed to provide better support for riders in a more leaned-forward position. Meanwhile, the CB650’s seat is slightly softer and more cushioned, making it suitable for longer road trips or casual cruising.

Ultimately, the choice between these two motorcycles will depend on individual rider preferences regarding comfort, ergonomics, and riding style. Riders seeking a more laid-back, comfortable ride may prefer the Honda CB650, while those looking for a sportier, more aggressive experience might opt for the CBR650.

Practicality and Maintenance

The Honda CB650 and CBR650 are both practical choices for riders who want a reliable and efficient motorcycle. In terms of fuel efficiency, the CB650 has an estimated 45 MPG (6.5 L/100km) on the highway and 38 MPG (6.2 L/100km) in the city, while the CBR650 has an estimated 43 MPG (5.5 L/100km) on the highway and 36 MPG (6.5 L/100km) in the city. While the CB650 has a slightly better fuel economy, the difference is not significant enough to make it a major consideration.

When it comes to storage capacity, both bikes have a similar amount of space for storing small items such as gloves, sunglasses, and phone chargers. The CB650 has a 1.3-gallon (5-liter) fuel tank, while the CBR650 has a slightly larger 2.0-gallon (7.6-liter) tank. However, neither bike has a large enough storage capacity to carry larger items such as helmets or luggage.

In terms of repair costs, both bikes have relatively low maintenance requirements and are generally reliable. According to Honda’s official estimates, the CB650 requires routine maintenance every 5,000 miles (8,000 km), while the CBR650 requires it every 6,500 miles (10,460 km). The estimated repair cost for the CB650 is around $300-$400 per year, while the estimated repair cost for the CBR650 is around $350-$450 per year. While these costs are not insignificant, they are relatively low compared to other motorcycles on the market.

Overall, both bikes have similar practicality and maintenance requirements, making them suitable choices for riders who want a reliable and efficient motorcycle. However, riders should consider their specific needs and preferences when choosing between the two models.

In conclusion, the Honda CB650 and CBR650 are both excellent choices for riders who want a powerful and fun motorcycle. While the CB650 has a more laid-back riding position and a slightly softer suspension, the CBR650 has a sportier riding position and a more aggressive suspension. Ultimately, the choice between these two bikes will depend on your personal preferences and riding style.
