KTM electric dirt bike
By Green Living Tips | Published  02/6/2009
Happy dance! KTM expects to start making a zero emissions electric dirt bike available from next year.

According to Hell For Leather, weighing just 90kg (198lbs), the bike weighs less than KTM's own 125cc enduro, but has the torque of a 250cc two-stroke.

While the zero emissions side is very nice as 2-stroke motorbikes emit more greenhouse gases per cc compared to a car, have you ever heard a 250cc two stroke dirt bike having its guts revved out? It's a noise straight from the depths of hell. It's brutal and it's got me beat how some of these bikes are even street legal.

KTM Zero Emissions (and noise) electric bike

Unfortunately, many dirt bike riders are either deaf from their hobby or just don't care about the impact of noise pollution, a very underrated issue.

A 250cc two stroke can be clearly heard kilometers away out in the bush and it really unsettles local wildlife (and some humans, like moi).

Environmental issues aside, someone who thinks it's great fun doing something that negatively affects such a wide area is being rather selfish in my opinion. It's a really destructive hobby.

The lithium ion batteries used in KTM's Zero Emission bike give it a range of about 40 minutes under "race conditions." It's not a huge range, but it's a start and it's still early days in the evolution of electric bikes. According to Hell For Leather, the bike will be "affordable", but no price range was provided. I certainly hope the price will be reasonable to encourage uptake.

I use a 125cc 4-stroke quad farm bike for getting around my block at the moment. While it's a lot quieter than a two stroke and more fuel efficient than hauling a full sized vehicle around, it's still too noisy in my opinion and I limit my use to work purposes only. Electric quad bikes are available, but unfortunately cost around the $35,000 mark at the moment; about 70x what mine cost.

You miss seeing so much wildlife when on a bike compared to on foot and I'm often baffled by hard core dirt bikers who choose to ride two-stroke monstrosities claiming to have an appreciation of the bush.

So, kudos KTM - let's see more dirt bike companies following suit!

    I am an avid outdoors person and appreciate the tips and updates available on your website. My family and I have continued to decrease our carbon footprint and are always looking at ways to improve our way of life through green living. I am extremely excited about the advances made in electric motor and battery technology to allow them to be used in a vehicle of this size and weight. I will be one of the first in line when KTM brings these to market.

    I would like to correct you on a slight misconception in your article. 2-strokes are actually quieter than the equivalent 4-stroke. I do race off-road motorcycles and sound testing is strictly enforced at sanctioned events. The 4-stroke has been a big focus by both the OEM's and the aftermarket due to this issue. 2-strokes of larger displacement (250cc-300cc) average sound testing places them at the low end of 90 decibels, whereas the 4-strokes of equivalent horsepower (450cc) will routinely test in the high end of the 98 decibel limit if they pass at all. The OEM's have realized this and are trying to work to meet the future sound requirements of 96 decibels, but have their work cut out for them. Kudos to Yamaha who has made a substantial effort and taken the lead in this area.

    In addition 4-strokes require substantially more maintenance to keep them in top running condition. They need 2-3 times as frequent oil changes (measured by hours run) and use 1.5 to 2 times as much oil. Granted this can be recycled, but it takes energy to produce this and is usually of a higher grade than the equivalent 2-stroke oil due to the way the engine works. There is also the increase in replacement parts required in a 4-stroke due to the higher wear and additional moving parts. Fuel efficiency is also dramatically less than a 2-stroke, though EFI is helping with this slightly.

    It is for all these reasons and the limited miles I ride that I opted for a 2-stroke. The newer 2-strokes are cleaner burning and may actually decrease the carbon footprint over the equivalent 4-stroke with all other issues factored in. I know this may be counter-intuitive to the majority of your readers, but they must look at the big picture. The fact is the combustible engine will be obsolete in the near future, but direction is yet to be determined. I welcome reading about strides made by Honda and other manufacturers in their newest hydrogen vehicle (Honda FCX Clarity), as I feel that battery technology will not be the long term solution. These manufacturers will not continue to invest great sums of money on these types of powerplants without our pressure and support. Therefore it's up to us to encourage them to advance their technology by supporting the appropriate products.

    Thank you again for your article and please keep us updated this vehicles progress.

    HI i am a motocross racer and have had ktms since theye were air cooled 50cc with the inch thick fender that you coudnt break, ive cant wait for th E-bike, a 90kg bike with the suposed torque of a 250 would dominate th race track, especialy idoors.
    The only thing concerning me is the hour charge limit, thats going to limit your riding.
    but it sounds like it will be gutless and slow. real dirtbikes like the KTM 300xc 2 stroke are probly goin to beway more fun than the E-bike cause they have much longer range and make much more power, without poluteing half as much as the average harly, or half as noisy.
    All in all the E-bike seems like a cheaper alternative that will provide more rideing for more people who dont like noise or power.

    just switch a battery, you can cycle 3 while charging.

    you can even use a portable generator to charge it up, not very green, but it would beat a 250 performance, value and pollution with no problem...

    after two or three years a better range battery would become available and since the engines won't improve much and won't wear down, it would be a straight upgrade, 5-10 years later you could do an engine switch involving 4 screws and some duct-tape :P

    electric motorcycles are going to be so cheap as time passes, people will buy them for their 14 year olds as birthday gifts :D
