V-Strom 650 ABS Info

Trying out the bike in the shop, but wrong colour and no ABS

I am getting the white version of this bike

From Wikipedia

The Suzuki V-Strom DL650 is a mid-weight dual-sport motorcycle manufactured in Japan by Suzuki and sold worldwide. It was launched in 2004. The name V-Strom combines V referring to the bikes engine configuration with the German word Strom, meaning stream or current.[1]

Unlike specialized motorcycles, the V-Strom 650 trades strength in a single area for adaptability to a variety of riding conditions: commuting, cruising, adventure touring and to a lesser degree off-road riding. In this respect, the DL650 resembles a UJM with a broad character taking the place of specific strength.




A 6-speed transmission mates to the fuel-injected and slightly retuned 645 cc liquid cooled, 4-stroke V-twin engine from Suzuki’s own SV650 sport bike. An upright,standard riding posture and 427 lb (194 kg) dry weight contribute to the bike’s handling characteristics.


The engine is a 90-degree, liquid cooled, 4 stroke V-twin, with 81 mm (3.2 in) bore and a 62.6 mm (2.46 in) stroke, four valves per cylinder, and intake and exhaust valving each with their own camshaft. More relaxed cam profiles over the SV engine boost the power between 4000 and 6500 rpm, along with slight changes to the airbox and exhaust. Relative to the SV, the crank inertia (flywheel effect) is also increased by 4% via a redesigned starter clutch.[2] As well, the DL650 engine uses a plastic outer clutch cover and engine sprocket cover for reduced weight and noise.[2]

In a significant departure from the SV engine, which uses cast iron cylinder sleeves, the DL650 uses Suzuki’s proprietary SCEM (Suzuki Composite Electro-chemical Material) plated cylinders, a race-proven nickel-phosphorus-silicon-carbide coating for reduced weight and improved heat transfer, allowing for tighter and more efficient piston-to-cylinder clearance[2], similar to a Nikasil coating.

Engine electronics

The DL650 employs sophisticated engine electronics for starting and throttle control and uses Suzuki’s AFIS (Auto Fast Idle System), eliminating a fast-idle control. The engine control module (ECM) reads engine information (ie, coolant temperature) via a 16-bit central processing unit (CPU) — controlling the fuel system’s dual throttle bodies and contributing to strong acceleration up to a rev-limited 10500 rpm.


The DL650 employs Suzuki Dual Throttle Valve (SDTV) fuel-injection and exhausts via a two-into-one exhaust system with a catalytic converter in the muffler. European models meet Euro 3 emissions specifications. In the US, a “PAIR” air injection system reduces CO and HC emissions.


A twin-spar aluminum frame and swingarm accommodates rear Showa mono-shock with a hydraulic preload adjuster. Front Showa shocks are pre-load adjustable. The DL650 uses a 19 inch front wheel, 17 inch rear wheel.

Instruments and bodywork

The bike’s instrument cluster includes a compact analog step-motor speedometer and tachometer (both with LED illumination) and a digital LCD unit with odometer, tripmeter, coolant temperature gauge, fuel gauge, LED neutral, digital clock, turn signal and high beam lights and an oil pressure warning light.

An adjustable windshield allows movement of 50 mm. A small underseat compartment, suitable for small tools, gloves, or an owner’s manual, can be accessed by removal of the seat, via a keyed lock located at the rear of the bike, just below the built-in rack.

[edit]Global sales and manufacture

Sold in Europe, Oceania and the Americas, the DL650 competes with the Aprilia Caponord and Pegaso, BMW F650 Series, and most directly, the Kawasaki Versys. The Suzuki DL650 is manufactured at the Suzuki’s ISO14001 certified plant in Toyokawa, Japan.

European model 2004 DL650, note the lack of small round side reflectors, shown with aftermarket crashguards, belly-pan, centre-stand and windscreen.

US Model 2005 DL650, with aftermarket windshield and bracket, hand guards, Givi crash guards, Suzuki tall seat, and top case.


The V-Strom 650 was named one of the “ten best” bikes under $10,000 by Motorcyclist (USA) magazine, October, 2007โ€”beating out, among many others, the V-Strom 1000. In a September 2006 article, Cycle World magazine wrote “the DL650 may just be the most shockingly competent machine in the world today.”[3] A 2004 article from MotorcycleUSA.com said “it was hard to imagine another machine with a competitive versatility-per-dollar ratio.”[4] Twice consecutively, the DL650 has earned the title “Alpenkoenig”, winning Motorrad magazine’s (Germany) grueling trans-alp multi-bike test in 2005 and 2006.[5]

Learning Python

After scanning through the archive Python articles at Clark’s Tech Blog I noticed a link to MIT’s MIT 6.00 Intro to Computer Science & Programming, Fall 2008

This subject is aimed at students with little or no programming experience. It aims to provide students with an understanding of the role computation can play in solving problems. It also aims to help students, regardless of their major, to feel justifiably confident of their ability to write small programs that allow them to accomplish useful goals. The class will use the Python™ programming language.

I have downloaded the episodes from iTunes Uni and the first lecture was quite good.
It brings back old memories of sitting in lecture theatres listening to the same concepst. The only difference is we used Pascal, which shows my age.

Ripping CD’s

I have just finished ripping these

Box of CDs

my CD collection, into Apple lossless audio files. Now I will never need to rip my music again because unlike MP3 or AAC files there is no compression, so converting from Apple lossless to another future lossless format means no audio quality is lost.

Converting to Apple lossless has blown out my music folder from around 120 gb to just under 160 gb

As you can see I am a huge fan of Podcasts and have a few audiobooks as well.
Itunes University is pretty good as there is a lot of good free stuff to watch and listen too.


After installing Snow Leopard on my Macbook I was excited to see if I could use OpenCL.
OpenCL is a technology to use your graphics card to do tasks that are traditionally done by the CPU

The most common example given is encoding videos. A video card, a GPU is substantially faster for some tasks.
For example in the benchmark below it gives an example of a Core 2 Duo (C2D) running at 3gz takes 12 seconds to perform the benchmark vs 0.93 seconds using the GPU!

My Mac being slightly older is slower still.

OpenCL introduces hardware decoding of H264 streams. That is instead of maxing out your CPU when playing a BlueRay disc it now offloads the work to the GPU, making your computer more responsive.

But, you need a Nividia 9600GT, my 8600M GT does not cut it ๐Ÿ™
