Aprilia Sonic 50

Scooter myself to nip to the shops, I have learned to love our sonic for its acceleration. It's not just pulling away from the cars when the lights change, but it is also catching up to the cars in front and overtaking them that really tickles me!

Hates.
I regret not transferring the warranty over when I bought the scooter. I still have time to do it but I hate to part with money and Aprilia want a whopping £30 off me just to change the name over. Not fair. So when the the speedo cable went at just 1000kms I decided to buy it myself. Then the winker relay went at 1200kms, then the front wheel bearing went, then the exhaust finally rotted away (at 7000kms)because of the rotten wet British weather. I had a new one fitted gaskets and all, then the tyre got punctured. "O.K" you may think. "It's just a puncture" which is just what it is. But I think dismantling the exhaust to remove the rear wheel is a bit extreme, especially when you have to order (and fork out for) new exhaust gaskets. Well, I have finally fallen out with my girlfriends' sonic. After its unreliability finally overcome me (because the starter motor has just packed up. "Use the kickstart"you say.

Yamaha XP 500 TMax

scooters have been on different planets ever since the days of the Mods and Rockers four decades ago. No self-respecting biker would be seen dead on a single-speeder and the same parents who’ll happily buy their a daughter a scooter to commute to college would freak out if she wanted a motorcycle.

Now Yamaha, which led the way with the 250cc Majestic in 1994, has tried to combine the best features of the two genres in the 500cc T-Max by endowing it with a number of big-bike features.

Conventional scooter design has the engine and transmission pivoting as a unit so they actually form the rear suspension, a practice that leads to high unsprung weight and shortcomings in handling.

The T-Max has its motor and belt drive rigidly mounted in the frame; final drive is by an enclosed chain running inside one arm of an otherwise standard cast-alloy motorcycle swing-arm. The suspension is entrusted to a horizontal pull rod-operated shock absorber, as used on Buells and other interesting motorcycles.

The front suspension is also well up to motorcycle standards: 38mm conventional cartridge forks, wheels that are 14" in diameter and shod with serious rubber - 120/70 in front and 150/70 in back, the same widths as my 750cc sport bike.

CBR1000RR

CBR1000RR is the lightest, most compact, and best performing motorcycle in its class, making it the standard against which all other literbikes are measured. And for 2009, it’s available with Honda’s high-tech electronically controlled Combined ABS for the ultimate in sport bike braking performance.

Performance and style. No two elements are more important on a sportbike, and the Honda CBR1000RR has them both in spades. Of course, when a bike is bred on the racetracks of the world using DNA gleaned from Honda's MotoGP championship-winning machines, would you expect anything but the best? And the CBR backs it up, packing state-of-the-art features like our available Electronic Combined Anti-lock Braking System (C-ABS) and the revolutionary Honda Electronic Steering Damper (HESD) that leave other literbikes on the trailer. Winning Road Racing World's “2009 1000cc Shootout” merely confirmed the CBR1000RR's supremacy, with 2010 certain to continue its legacy of class-defining power, light weight, handling and looks (checkout the three stunning colors).

- Compact, liquid-cooled DOHC 16-valve 999cc four-stroke inline four-cylinder engine features bore and stroke dimensions of 76mm x 55.1mm.
- Removable cylinder block with Nikasil-coated cylinders.
- Sixteen-valve cylinder head features 30.5mm intake and 24mm exhaust valves with a 12.3:1 compression ratio for efficient combustion and high horsepower.
- Larger titanium intake valves create a lighter valve train and feature double-spring design for optimum performance at high rpm.
- Intake ports use latest shot-peening technology that improves power and torque characteristics.
- Cam-pulser location between the middle cylinders allows a narrower cylinder head and frame.

Yamaha Stryker

Befitting a bike of the custom cruiser genre, the Stryker boasts raked out front forks with a large 21-inch front wheel, a chunky 210-section rear wheel, and the fuel tank features flame decals to add to its take-no-prisoners attitude. Low bars, minimalist fenders and a low-slung one-piece seat also contribute to the custom chopper look.

The dual exhaust pipes have been thoughtfully bent to improve aesthetics and the front and rear wheel guards are made from steel.

The 2011 Yamaha Stryker's rear brake light is comprised of LEDs and it's possible that the design may have more appeal than the Honda Fury with its plastic rocker covers. Colours include Impact blue, Reddish copper and Raven black.

• 1304cc (80 cubic inch), liquid-cooled, short stroke, SOHC, 4-valve per cylinder, fuel injected, 60° V-twin powerplant pumps out impressive power and torque for excellent cruising performance.

• Uneven firing interval, bore & stroke dimensions and special ignition & injection mapping all contribute to excellent torque output and that classic V-twin pulse feeling

• Liquid-cooling not only allows for higher state of tune because it maintains more stable operating temperatures, but also reduces mechanical noise for a quieter engine.

• In an effort to maintain the classic air-cooled appearance of the engine, cooling fins have been added as a styling highlight.

• The short stroke engine design reduces the “height” of the engine, while the 60 degree “V” makes the engine more compact thereby centralizing mass and lowering the center of gravity for lighter, more responsive handling.

• One-piece cylinder heads feature 4-valves per cylinder to provide optimum breathing efficiency for maximum power output.

• Stylish chromed cylinder head covers.

• The SOHC valve train features 36mm intake and 32mm exhaust valves with special single coil springs for great power and torque. Valves angles are set at 20 degrees from centre.

• Specially designed roller rockers activate the valves. The rocker system allows a greater amount of valve lift without causing excessive camshaft wear and friction. The slipper portion of the rocker arm features a needle bearing which reduces wear and slide resistance (friction). The camshafts have been specially designed for use with roller rockers.

• Mikuni dual bore, 40mm throttle body fuel injection system with TPS (Throttle Position Sensor) and ISC (Idle Speed Control). This is a “closed loop” system that utilizes an oxygen sensor in the exhaust. The sensor “sniffs” the spent exhaust gases and feeds back info to the ECU which in turn adjusts the fuel/air mixture for maximum power with minimum emissions. The oxygen sensor is located before the mufflers, so the use of slip-on mufflers will not affect this system. Each injector features 12 holes and a dual spray pattern for better fuel atomization and more complete combustion chamber filling. There is one injector per cylinder. Fuel injection benefits include improved fuel economy; choke less operation, reduced emissions, and smoother running.

• High pressure fuel pump is located in a separate sub tank below the seat.

• 2 into 1 into 2 exhaust system features dual slash cut mufflers which provide a specially developed exhaust note that accentuates the V-Twin rumble. The engineers call it the “sound of acceleration”.

• A 3-way honeycomb catalyzer is located at the entry point to the mufflers. The catalyzer reduces harmful exhaust emissions.

• Smooth-shifting, 5-speed transmission with 5th gear o
