Metzeler Sportec M-3 tires, What every Bike Needs


Tires make your bike the ride it can be. The Metzeler Sportec M-3 tires, more sport, more tech. Open-class sportbikes have achieved a 1:1 power-to-weight ratio - that is, the most powerful models now make one horsepower per kilogram.

Such remarkable performance makes it increasingly difficult for a tire manufacturer to achieve what Metzeler calls the 'Holy Grail', a sport tire that's sticky yet durable. That's the aim of the new Sportec M-3, which slots between the existing Sportec M-1 and Racetec in Metzeler's sport tire line.

Beyond those seemingly contradictory desires, the M-3's design brief specified a tire that performed the same throughout a single riding session and its entire life cycle, meaning many heat cycles. Thus the front tire was made stiffer to snap into corners quicker, its steel belts were softened to let the tire 'talk' to the rider and its multi-radius profile was smoothed for enhanced stability.

Clutch Play, the Slipper Clutch


Using the clutch lever is one of those tasks you perhaps feared as a beginner, but soon became familiar with. You pull in the lever snick the gearbox into first, give it a little gas, ease out the clutch and roll away As long as you don't stall the engine or wheelie over backward, you go merrily on your way, using the clutch only when you need to change gears, come to a stop or pull away from one.

That's fine for the vast majority of street riders. But if you want to get the most out of your motorcycle, there's a whole another level of clutch play.

The first thing you need to do is make sure your clutch lever is adjusted correctly. You want the engagement point to fall comfortable within the reach of your hand, not too close or too far from the grip. On hydraulic clutches, simply change the setting on the levers thumbwheel adjuster; on cable clutches, vary the amount of free play at the lever or down by the actuator. Be sure not to completely eliminate the free play or the clutch may slip. Your owner's manual will tell you how much play is correct.

Building a Harley-Davidson Screamin-Eagle Engine


After digging into the inner workings of several big-inch engines over the past several years, we thought it was time to see what Harley-Davidson has to offer. Along with the standard 223.52cm (88inch) Twin-Cam engine that equips most of their 2005 motorcycles, you can have a big-bore of 241.3cm (95inch) or the insane 261.62cm (103inch) stroker engine.

Having said this, we must explain that there are a few rabbit trails that you have to follow to get a big engine from Harley-Davidson.

First, if you want a 241.3cm (95inch) motor, it is only available through the Genuine Parts channel, as parts kit or as separate parts to convert an 223.52cm (88inch) Twin Cam engine. A few years ago, Harley offered these engines in special edition CVO bikes, but as of June 2005, there isn't a production bike available with the big-bore engine.

The engine's increased displacement is arrived at by increased its bore from 3 3/4inches to 3 7/8inches. This can be done by either having your stock cylinder bored out at your local bike shop (which is direct a problem in Thailand) or buying a set of big-bore cylinders from your Harley dealer.

Motorcycle Loading Ramp


For things with a engine, Thailand is will known for two products around the world, the first is the amount of small motorcycles the second is the quantity of pickup trucks you see, it sometimes looks like everybody has a pickup truck.

Small engine motorcycles or scooters are great for transport in the cities, but are not that comfortable doing intercity travel.

So why not load the motorcycle in the back of the pickup truck, true but even if a small motorcycle doesn't weight as much as there big brothers, they still can be an uncomfortable load to get in the back of the pickup truck.

With two motorcycles in the back, driving upcountry on a highway, which seems endless to European standards.
