THE fun will stop if you are injured in a motorbike crash. So one vital piece of safety gear is your helmet.

Choosing one is subject to a rider's needs, fancy and how much he is willing to pay.

For the next two weeks, Biker Boy will review five helmets, starting with three today.

You can even stand to win one, courtesy of helmet manufacturers KBC, Nolan and AGV. (See report on facing page.)

1.KBC DRT-X Combat

Scare your motocross rivals with the DRT-X's fiery graphics, which look like something out of a superhero comic strip. Constructed using an advanced alloy polycarbonate resin, the US-designed, high-energy absorption helmet weighs 1.5kg, and costs between $188 and $210.

For those new to dirt-riding, the Snell/Dot-approved DRT-X is easy on the pocket.

Its double D-ring chin strap keeps the helmet from shifting while you ride over uneven terrain.

The long visor blocks flying debris and the ample space near the chin bar does not make you feel claustrophobic.

A recessed portion on the removable and washable inner liner ensures that you are not riding with ears uncomfortably folded.

Most importantly, its light weight means you have the stamina to ride longer.

During testing though, the centre plastic bolt securing the visor came loose, causing the visor to move up in the wind. This can be easily solved using a sealant or a washer.

Like most matte helmets, a wipe-down with a wet cloth is a must to ensure the helmet surface stays clean.

2. Nolan N103

When it comes to touring, the N103 fits the bill.

Its chameleon-like features - being able to switch from a full-face to an open-face helmet in the blink of an eye - may appeal to some riders.

Unlike full-face helmets, you do not have to shout to talk to your pillion - just use the switches near the chin bar to flip. It will become second nature with use.

The system is built to prevent the chin bar from accidentally flipping up in a crash.

The Italian-made helmet from Chong Aik International weighs about 1.8kg and retails for $350.

The weight of the polycarbonate helmet was noticeable when we first put it on, even though the inner liner was smooth as silk.

But like the Dual Action opening system, you will get used to it.

In full-face mode, the N103 cuts noise levels efficiently, except for the slight wind gush at the top of the helmet.

Some may prefer the simple double D-ring-type chin strap, but the ratchet-type chin strap on the N103 is faster to secure.

Other features like a sun visor and an optional communication system are a bonus for serious bikers.

3. KBC TK-8 Swirl

This entry-level helmet is the most popular in the KBC helmet line-up.

While its basic polycarbonate construction is no-frills, the bold graphics on this PSB-approved helmet scream for attention.

Priced at $150, the 1.7kg TK-8 is a steal. Features include a washable and removable inner liner, plus a 'no-tools required' removable anti-fog visor.

Peripheral vision is wider than some helmets, ensuring better safety.

The vents at the sides of the chin bar slide to let air flow freely into the helmet, but constant sliding may cause the part to rattle over time.

While the inner liner absorbs perspiration well, the chin strap covers look like they will need replacement sooner than later.

As an 'everyday' helmet, the TK-8 offers great value for money. Replacement parts are cheap - a visor costs $30, while an inner liner $42.
