Cleaner motorcycles or face the chop!

Leave a comment

Euro 4 emissions laws have already hit most supersport models, many air-cooled bikes, single-cylinder adventurers and most Japanese cruisers and now more models either make significant updates or face the chop under Euro 5.

The new laws come into effect for new models from 2020 and existing models from 2021.

Already there is talk about some of the models that face the chop unless they have major updates.

For example, both the Honda CBR 1000RR Fireblade and Yamaha YZF-R1 will not comply with Euro 5 requirements.

Chop or cleaner emissions?

One of the solutions to the tighter emissions laws could be variable valve timing (VVT), which is common in cars.

VVT makes the engine more flexible in different conditions, resulting in increased fuel economy, lower emissions and improved performance, particularly torque.

It is already used in Suzuki’s GSX-R1000, several Ducatis and BMW’s new Shiftcam technology.

Recent patent filings in Japan reveal Yamaha will not scrap the R1 but make significant upgrade including VVT and a MotoGP seamless gearbox.

Meanwhile Honda has filed a patent for VVT to replace their VTEC system, so it could be used in the ‘Blade.

Emissions historyLoud pipes trial chop

The European Union emissions standards started in 1999 with Euro 1, followed by Euro 2 in 2003 and Euro 3 in 2006.

There followed a more-than-10-year gap before the tough Euro 4 regulations virtually halved the limits for carbon monoxide (CO), hydrocarbons (HC), and oxides of nitrogen (NOx).

Not only that, but the limits still had to be met after 20,000km of use.

Euro 5 is even more strict, cutting the limits almost in half again.

They will also require a more advanced onboard diagnostic system and motorcycles will be required to meet emission targets for the life of the bike!

It’s a big ask and it has the engineers scrambling for solutions that won’t make every bike an expensive technological nightmare.

What motorcycle models face the axe?

Leave a comment

Tough European emissions laws threatened to axe several much-loved models last year, but it seems many have had a stay of execution.

The Euro 4 rules introduced in 2016 were almost 50% tougher to pass.

For example, Euro 3 required a motorcycle to pass an emissions test when new, or after 1000km. Under Euro 4 they have to still be compliant after 20,000km or 35,000km depending on the size of the machine. 

Because the requirement was so tough, the European Commission (EC) allowed a couple of years for compliance.

That ended on December 31 2018 and many models are now no longer able to be sold in Europe and several other countries that follow the same stringent rules, such as Japan.

The axe has now fallen on most supersport models, many air-cooled bikes, single-cylinder adventurers and most Japanese cruisers.

Axe reprieve

However, manufacturers are still making some of the models that looked like failing the tougher tests, strictly for markets where the Euro 4 rules do not yet apply. They include Australia, the USA and South Africa.

That is a big enough market to make it economically viable to continue production of bikes that continue to sell well, such as the Suzuki Hayabusa.

Suzuki Australia and the USA made special mention to customers that the model would continue in their markets.

The hyperbike will eventually be replaced by an updated Hayabusa, but in the meantime, the factory will continue to make the bike for non-Euro 4 markets.

When it does return to worldwide production, the Hayabusa may not even be Euro 4 compliant.

It may be Euro 5 compliant as that standard is coming in 2020 for new models and 2021 for existing models. 

But once again there may be a reprieve from the axe. That’s not because it’s too tough, but simply because the EC has not yet agreed on the exact standards and testing methods.

Emissions reducedLoud Pipes exhausts mufflers blitz axe

Since 1999, the motorcycle industry has gone from Euro 0 to Euro 4 and reduced emissions by 91%.

Despite those reductions, most motorcycles are now more powerful and economical than they were at the end of the last millennium.

And even though sceptics said the technology would make motorcycles more expensive, they are no more expensive in real terms.

Euro 5 will lead to new motorcycles that will have a range of solutions to the emissions problem.

That will include, but won’t be limited to, leaner burn, liquid cooling, forced induction, hybrid technology and, of course, electric power.
