Continental ContiClassicAttack vs Metzeler Lasertec: retro tires compared

If you ride a classic BMW, these two names come up every time: the Continental ContiClassicAttack and the Metzeler Lasertec. They are often mentioned in the same breath as retro tires, but that puts you on the wrong track. These are two fundamentally different tires: one is a modern radial in classic sizes, the other a classic bias-ply tire that has been kept up to date. That difference decides which one belongs on your bike.

The real difference: radial versus bias-ply

The ContiClassicAttack is a radial tire. Continental builds it with a 0-degree steel belt and modern technology such as TractionSkin, a tread surface without the slick mould-release layer, which makes the break-in period short and safe. The tread pattern is not ribbed or vintage: it is a modern design, closely related to Continental's modern sport touring tires. The goal is not to look old, but to give your classic modern road manners.

The Metzeler Lasertec is the opposite story: a bias-ply tire that descends directly from the Metzeler Laser line of the eighties. The classic tread look has stayed, while the rubber has been kept up to date with a silica-rich compound. This tire is made for classics from the seventies and eighties that want to keep their original character.

In short: choosing between these two mostly means choosing between modern radial handling and authentic bias-ply character.

The Continental ContiClassicAttack: a modern radial in classic sizes

Construction and technology

The 0-degree steel belt keeps the tire stable at higher speeds and lets it steer precisely. TractionSkin shortens the break-in period considerably. This is current tire technology, packaged in sizes for older bikes.

Road behavior

The ContiClassicAttack behaves like a modern tire, because that is what it is. It turns in lightly, stays stable in long corners and grips well on both wet and dry roads. If you switch from bias-ply to this radial, you will immediately notice how much lighter and more direct your bike steers.

Sizes and fitment

This is where you need to pay attention. The ContiClassicAttack only exists in 18 and 19 inch radial sizes: 90/90 R18 and 100/90 R19 for the front, 110/90 R18 and 120/90 R18 for the rear. That covers a lot of classics, including BMW airheads such as later R80 and R100 models on 90/90-18 front and 120/90-18 rear. It does not fit the BMW K75, K100 or K1100: a K100 needs 100/90-18 front and 130/90-17 rear, and Continental does not make those sizes in this line.

The Metzeler Lasertec: the classic line, kept up to date

Heritage and look

The Lasertec is not a replica of fifties or sixties tires. It descends from the Metzeler Laser line of the eighties (the era of the ME33 Laser) and is aimed at classics from the seventies and eighties. The tread pattern matches exactly that generation of motorcycles.

Road behavior

The silica-rich compound gives the Lasertec grip that riders and reviews actually praise in the wet, and the tread disperses water well. It is a stable, predictable all-rounder. To be fair: a bias-ply carcass steers heavier and less precisely than a modern radial, and you reach its limits sooner when riding hard. For touring and daily use that is no problem at all; if you want maximum handling, the radial is the better tool.

Sizes and fitment

The Lasertec comes in a wide range of classic sizes, including the K100 sizes: 100/90-18 front and 130/90-17 rear. The common airhead sizes 90/90-18 and 120/90-18 are also available. For the BMW K series this makes the Lasertec the obvious choice of these two.

Direct comparison

Which tire fits your bike and riding style?

Choose the Continental ContiClassicAttack if you:

• Ride a classic with 18 or 19 inch wheels in the available sizes, for example an R80 or R100
• Want modern handling: light steering, stability and plenty of grip, rain included
• Use your bike all season and simply want to trust your tires
• Have no problem with a modern tread pattern on a classic motorcycle

Choose the Metzeler Lasertec if you:

• Ride a BMW K75, K100 or K1100: of these two, this is the only one available in the right sizes
• Want the classic tread look on your restoration or period-correct build
• Are looking for a proven all-rounder with good wet grip and decent mileage
• Appreciate the original, calmer steering character of a bias-ply tire

Practical tips when switching

Never mix radial and bias-ply. Fit the same construction type front and rear, and preferably replace tires as a set.

Check your sizes. Your type plate and manual list the original sizes. Switching from bias-ply to radial can be a real upgrade, but have a specialist confirm it makes sense for your model and rims.

Tire pressure matters. Check it regularly, especially with changing seasons. It is the cheapest handling upgrade there is.

Break in new tires calmly. TractionSkin shortens the break-in on the Continental, but give any new tire around 100 km before you fully trust it.

Watch the age. Classics often age their tires out before wearing them out. Check the DOT code: a tire with plenty of tread can still be past its prime. Store your bike cool and dark.
