Member reviews: 2017 KTM Fogo 271

The following is a long-term review of a KTM Fogo 271 which at the time of writing, I have had the pleasure of owning for the last 16 months.

I have long had a passion for hardtail mtbs, be them analogue or pedal assist and have found the eMTB version through ownership of the superb KTM Macina Race, to make the perfect bike for wet weather/winter use.

Wanting to upgrade from the Macina Race, I had already decided that whatever
the next bike was going to be, it needed to be 27.5” ‘plus’ size and just as the Macina Race, it also needed to have a good component specification. I was also keen to stay with both the KTM marque and Bosch drive unit system.

After a bit of research, I opted for the KTM Fogo, which on paper exceeded my requirements by a significant margin and over time through use, has proved to be my perfect bike.

The Magura Boltron T-20×110 front forks as fitted to the bike was an interesting one for me as I have read so many reports, both good and bad, which made me keen to own a bike that had them fitted just so that I could come to my own conclusion about them. I have also previously been asked privately about the forks and what I knew about them, so at least I finally got to discover for myself and can offer opinion accordingly, and not just based from hearsay.

As it happened, this unknown gamble in respect of the front forks has proved to be worthwhile, and I really do love the compliant feel of them and for the most part they suit my riding style perfectly. They have also proved to be the most hassle-free and reliable front fork that I have ever owned. Before deciding upon this bike, I thoroughly researched the front forks and quickly came to the conclusion that any issues with them were simply down to poor set up and understanding of the fork by owners, which ultimately leads to seal failure.

They possibly aren’t without fault though, and they certainly have weird handling characteristics, which can be a bit disconcerting if you didn’t know about it. Under braking the forks twist slightly which make the bike pull to the left. It is only really evident when riding on the road and once aware it, you kind of compensate in advance of it happening and soon became unaware of it. This also leads to one other issue though, which is the front brakes of the bike. The 180mm front disc is really a bit undersized for the bike, but I’m not convinced that the front fork could cope with a larger disc size. I do intend to try it sometime though, as it is about the only upgrade that after about 16 months of ownership of the bike, that I would like to make to it. The rear brake is more than up to the job, and I certainly have no complaints about it.

Staying for a moment with the front forks, in use they have possibly had to put up with more abuse and adverse riding conditions than could perhaps be expected of any eMTB and have only given my concern once, which was when we had the bad snow conditions in February 2018. I went out for a night ride in what must have been the coldest conditions that I have ever ridden in, and after about two hours of being out, with the bike completely covered in solid ice, the forks suddenly compressed and would not return. Moisture on the stations had frozen and that was it. I had to return home, riding with them fully compressed. Come the morning, they were back to normal, and have never been a problem since. I had intended to rebuild them soon but cannot find either the oil capacity or air gap, so they are going back to Magura for the work. At £92.00 including return postage, it probably isn’t worth my while rebuilding them anyway.

Part 2 continues below….

203mm on the front wont be a problem as it is just an adaptor so the caliper would be 23mm taller on the front fork mount so would not be a problem.

as for the rear you might have a clearance problem with the caliper fouling the frame but only way is to try it and see.

the main reason i have 203mm front and rear is to save on disc pads as heat kills even sinterd pads in no time. View attachment 29106
180mm is the maximum that the Boltron forks could take, simply because there is too much flex in them already.

The good news is that a friend come bike shop owner has offered me a 'no brainer' deal on a set of superb MRP Ribbon coil forks. I already have a few other friends that use them, and have yet to hear one bad thing about them. On the plus side, changing them gives me an increase in fork travel from 120mm to 150mm, the distance from the centre of wheel spindle to the bottom of the steerer tube is just 4mm longer than the Boltron set up, so I'm not going to worry about that, and I can then run a 203mm front disc quite easily, and also fit something that I have long missed with the Boltron set up, my RapidRacer Neoguard. I've really missed that, not that spray has weirdly ever been an issue with the Boltron set up.

And I forgot to say again , fantastic composition on taking pics. The boy ( well like me not so much boy now) certainly has an eye for detail. I always enjoy reading/looking at Ed's posts.
