V-Twin Cylinder Bike Engine

Harley Davidson Road King Engine

      Most V-twin engines have a single crank pin, which is shared by both connecting rods. The connecting rods may sit side-by-side with offset cylinders, or they may be "fork & blade" items with cylinders in the same plane without an offset.

     Generally, any two-cylinder engine with its two cylinders arranged more than 0° and less than 180° apart is referred to as a V-twin. Although Ducati use the name "L-twin" for their 90° twin engine (with its front cylinder nearly horizontal and the rear cylinder almost vertical), there is no technical distinction between V-twin and L-twin engines; and these are merely names used by convention.

   A 90° V-twin will, with a correct counterweight, yield perfect primary balance, although its firing intervals are uneven. A V-twin with an angle of less than 90° is more compact and has more even firing intervals, but has significantly poorer mechanical balance. Offset crankpins are sometimes used to reduce the resulting vibration.

Naza Blade 650R GTI  

    As for the more powerful 200kg Naza Blade TBR 650R with a 650cc motor providing significantly more power, it gets an additional 3.6bhp for its standard 79bhp, for a total of 82.6bhp, still torque is unchanged at 67Nm at 7,250rpm, while an additional gear gets thrown into the mix allowing you to shift up to 6th.

      The TBR 650R also uses the same set of 17″ rims and disc brake setup as the TBR 250R , except the tyres get swapped out for a larger set at 120/60 up front while a 160/90 tyre gets used for the rear and high performance steel braided line with red protective sleeve gets added into the mix.

Ducati 848 Evo 

      The Ducati Superbike 848 EVO is the lightest superbike ever built by Ducati. The EVO model is 6 hp stronger than the standard model, boosting the power up to 140 hp. The torque was also increased to 10 kgm resulting in a sharper acceleration and a flowing power delivery. The engine is combined with a lightweight 2-1-2 exhaust system equipped with a catalytic converter and 2 lambda probes to conform to Euro3 regulations.

 

      The bike features a magnesium front subframe which helps to geep the overall weight to as low as possible. Moreover its construction provides secure support for the headlamp, instruments and fairing. The stopping power is assured by radially mounted Brembo Monobloc callipers. The twin Monobloc callipers each have four 34 mm pistons that grip 320 mm discs to help generate a strong braking. The rear wheel is stopped by a Brembo two-piston calliper which bites a 245 mm disc.

Suzuki Gladius 650 V.

     The motor for instance doesn’t follow class wisdom because while Honda, Kawasaki and Yamaha have opted for parallel-twins and an in-line four, the Hamamatsu concern chose a small V-Twin. Displacing 645cc it produces a healthy 71hp at 8400rpm and 64Nm at 6400rpm, which isn’t too far away from the bike of the moment, the Yamaha MT-07.

     The chassis hardware bits are more conventional. The frame is a steel-tube trellis while suspension consist of 41mm forks at the front and a single rear shock at the back, both adjustable for preload. Unlike its Japanese rivals, the Gladius comes with ABS as standard (as opposed to being optional or not offered at all), which is a bit of a coup for a CBU bike with a retail price of RM39,750 including the dreaded 6 per cent GST.

In-line 2 / Parallel-Twin / Inline-Twin / Vertical-Twin

       A straight-twin engine, also known as straight-two, inline-twin, vertical-twin, or parallel-twin is a two-cylinder piston engine which has its cylinders arranged side by side and its pistons connected to a common crankshaft. Compared to V-twins and flat-twins, straight-twins are more compact, simpler, and usually cheaper to make, but may generate more vibration during operation.

       Different crankshaft angles are used in four-stroke straight-twins to achieve different characteristics of firing intervals and engine balance, affecting vibrations and power delivery. The traditional British parallel twin (1937 onwards) had 360° crankshafts, while some larger Japanese twins of the 1960s adopted the 180° crankshaft. In the 1990s, new engines appeared with a 270° crankshaft.

     Straight-twins have the advantage of being more compact, relatively simple, and cheaper to make in comparison to V- or flat-twins. They may be prone to vibration, either because of the irregular firing interval present in 180° crank engines or the large encountered reciprocating mass in 360° crank engines. Inline-twins also suffer further from torsional torque reactions and vibration.

Choose Your Bike (Part 2)

          Continue with type of bike that suit your life style. In previous post, I have write about limited by own ability (less electronic), great/fantastic speck, appearance/comfort and comfort/luggage/pillion bike. Those bike are very awesome but limited in functionality. What about if try a different way of adventure in extreme condition like in the desert or explore the canyon ? Or for touring that can suit different type of road. These are the bike you searching for  :

    

          If you want to run off-road and fun is your spec, the dirt trail and dual purpose bike is for you. Consider the new super motard class such as Suzuki V Storm and BMW R1150GS. 

      

       If you want to go for a long journey touring and performance, comfort, luggage and rider features is your style. Then the sport touring is for you. Both Honda and VFR800 and BMW K1200RS are good choice.

      Those bike I have mention in this post and the previous post required different kind of riding skill. After you have got skill in how to handle your bike on the road, how about upgrading your skill in the racing track. Than you will need high performance racing spec bike full with high quality of electronic control system.

   

           Street credibility bike for you to try the racer class or traditionally big replacement bore super-bike. Look at Suzuki GSXR1400 Hayabusa, Honda CB1000RR, Kawasaki ZX10R, Ducati 1299 Panigale or Aprilia RSV4. 

          How is that about the categories of bike I have mention about? Pick your bike that suit you. But if after consider all these, you are much more practical and you want a bike that more practical and minimal use of fuel to get to shop or work, than the scooter is for you. Consider Vespa, Honda Scooter and so on.
