The sound of two-stroke race bikes will once again thunder through the streets on the Isle of Man, as Ian Lougher is set to race the Suter MMX 500 at this year’s Isle of Man TT. The 576cc V4 two-stroke Suter has already made its debut during the TT, last racing during the 2016 edition of this iconic road race, though with lackluster results (121+ mph best lap) due to mechanical issues. Hoping to right that wrong, Lougher will once again climb aboard the Suter MMX500, and no matter what the result sheets say, we are sure the fans along the Manx hedgerows will enjoy his effort. Lougher has 30 years of experience on the Mountain Course at the Isle of Man, and in that time he has racked up 10 Isle of Man TT wins, along with an impressive tally from the North West 200 (8 wins) and Ulster Grand Prix (18 wins).
By my nature, I am a critical person. This isn’t exactly a desirable personality trait, but it serves me well in my chosen profession. Accordingly, I rarely ever use words like “perfect” or “flawless” when describing something. It’s just not in my nature. From my lens, there is always room for improvement. But, when it comes to seeing the Suter MMX 500 up-close and in person, I had to rethink my usual choice of words. I will sidestep superlatives and simply say that the Suter MMX 500 is a true rider’s motorcycle. On the Suter MMX 500, there are no electronic rider aids, no ride-by-wire throttles, no kickstands, mirrors, or lights. There is nothing on this machine that doesn’t serve a purpose, and the only acceptable purpose is to go as fast as possible.
I am about to ruin your day, because I am going to show you something that you will want very badly, but can’t have. It is what happens when you have the best of both worlds. It is the two-wheeled version of having your cake and eating it too. This machine is called the Yamaprilia, and as the name implies, it is a mashup of the Yamaha RZ350 and the Aprilia RS250. Using the two-stroke, twin-cylinder engine from the RZ350, and the twin-spar aluminum chassis of the RS250, owner Gareth Evans is looking for the best of both worlds. The build is an interesting one – and is featured by our friends at BikeEXIF – as it involves Evans fabricating more than a few parts himself – something that is easier to do when you have a background in mechanical engineering, like Evans does.
Fuel injection has finally come to the two-stroke market for production motorcycles, with KTM (and thus also Husqvarna) debuting two enduro machines with transfer port injection (TPI) on their single-cylinder smokers. This has been a long time coming in the two-wheeled space, even though we have seen TPI and direct injection on other two-stroke vehicles, like snowmobiles and personal watercraft for quite some time now. KTM is really the last manufacturer to support two-stroke motorcycles though, so any progress in this space is a welcomed breath of life for off-road riders. New technology truly could be the savior to two-stroke motorcycles, as emission standards continue to become more restricted with each passing year.
We shouldn’t be surprised to hear that Husqvarna will be following suit with its Austrian sibling, and adding fuel-injection to several of its two-strokes enduro motorcycle for the 2018 model year. After a long history of rumors and development, KTM finally debuted fuel injection for a production two-stroke model just a few weeks ago, using the technology on two of its upcoming enduro models, the KTM 250 EXC TPI and KTM 300 EXC TPI. Husqvarna will use the same technology for its own motorcycles in the same segments, announcing today the the all-new 2018 Husqvarna TE 250i and 2018 Husqvarna TE 300i enduro models with transfer port injection.
In Episode 48 of the Two Enthusiasts Podcast, we didn’t set out to talk about all the weird technologies in the motorcycle industry, though our conversation certainly covered its fair share of them.
We start the show talking about the Vyrus 986 M2 supersport, which features a unique hub-center steering chassis. This leads us into a conversation about the supersport market, and the rumors that Suzuki is bringing out a new GSX-R750.
From there, Quentin breaks some news that a reliable source has told him that there will be a new Suzuki GSX-R600 for the 2019 model year, which goes against what had previously been rumored. We then finish up the Suzuki talk with a quick discussion about the Suzuki Hayabusa, and hyperbikes in general.
The show ends with us talking about KTM’s new fuel-injection for two-stroke dirt bikes, and what that means for that segment of the industry. Q also tries his best to explain how transfer port injection works, though we would recommend googling some visual adds when you get to that portion of the show.
A fun show, though we think you will also find it very insightful as well.

The day has finally, come. The rumors can finally be put to rest. Fuel injection for production two-strokes is officially a thing, thanks to the clever minds at KTM. The Austrian announced today that it will bring fuel injection technology (called Transfer Port Injection) to its 2018 enduro lineup, which will debut later this May. Two KTM models will have the new technology, the KTM 250 EXC TPI and KTM 300 EXC TPI, and they will be coming to the global market. For the USA and Canada, a third model will come to market as well, the KTM 250 XC-W TPI. Fuel injection for two-strokes promises better fuel consumption, and it means that riders no longer have to pre-mix their fuel. KTM says that its transfer port injection technology provides a whole new experience for riding a two-stroke motorcycle, with better power and rideability.
Fresh from the office of the USPTO, we have confirmation that Honda has just received the patent for the first ever three-stroke motorcycle engine.
As you would expect, the unconventional engine design incorporates the power-to-displacement efficiencies of a two-stroke smoker, with fuel-to-power efficiencies of a four-stroke motor.
For many in the space, the three-stroke engine has been the Holy Grail of engine designs, with many OEMs rumored to have been working on a three-stroke engine.
Still, it is surprising to see the engineers at Honda claim the prize, as the Japanese brand up until recently has been heavily committed to its four-stroke technology.
Obviously, the engine technology can obviously be applied to any internal combustion application, however what makes this news especially A&R worthy is that Honda’s patent specifically states the engine’s purpose in two-wheeled vehicles, watercraft, lawnmowers, and generators.
It looks like Europe’s new Euro4 emissions standard has claimed its first victim (if you don’t count the exhaust pipe on the Ducati 959 Panigale), as neither KTM nor Husqvarna will be producing their 125cc two-stroke enduro models for 2017, and the foreseeable future afterwards.
The move is a euros and cents decision, and a slightly complicated one at that, but it boils down to the fact that making the small-displacement smokers meet the more stringent Euro4 emissions requirements was financially prohibitive.
Two-stroke fans were stoked to hear of Suter Racing building a 500GP-styled superbike smoker, the Suter MMX 500. The 576cc, V4, two-stroke machine promises superbike power coupled to a GP-level punching weight, 195hp and 280 lbs respectively, with modern suspension and chassis design. Only 99 specimens of the Suter MMX 500 will be produced though, each costing CHF 120,000 – roughly $125,000 or €109,000. And now, one of those machines has been tapped for racing duty, as Suter will be competing in the 2016 Isle of Man TT. Therefore, expect to see the Suter MMX 500 racing in the RST Superbike and PokerStars Senior TT races, with Ian Lougher behind the handlebars.
Do you ever go for a ride in the woods, come home smelling like pre-mix, only to lose that sweet scent once you finally take a shower? Has the move to four-stroke machinery greatly reduced your ability to woo a worthy partner to make “brap brap” noises with throughout the night?
Never fear dear reader, we understand your plight. Behold, 2 Stroke – a manly cologne that has been scented from the smell of two-stroke machinery, with hints of pine and spruce. Your braplife needs this.
