Full Test: 2008 KTM EXC

Moto Online travels to to find out if KTM’s ’08 EXC models in the orange army up to expectations.


and styling

KTM’s goal of its entire range of enduro EXC looking and feeling very to each other has definitely a reality. From the 250 EXC-F to the 530 these three models all and behave basically the same from the obvious engine

In 2007 the SX motocross range a major overhaul and looked different than in previous That same look has applied to the EXC enduro range time around, and the lights and enduro parts help the look off even better the motocross models.

The side and complete plastics are much minimal compared with the models, and they are designed to be weight. The radiator shrouds holes to allow air into the after it flows underneath the

The front ends of the new EXCs tough, with a single headlight giving the KTMs a new ‘face’. The lens is made of polycarbonate, and is light weight most parts on the bikes.

The end has a mudguard similar to that on the bikes, although it has an LED taillight There’s also a numberplate with indicators that is to be taken off easily for racing

The fuel tanks on the new EXCs all excellent knee grip to the holes that double as intake holes, and all models their own specific fuel (9.2 litres for 250 EXC-F and 9 450 and 530 EXC-R models). A new fuel cap requires the rider to push a to get it to rotate, putting an end to the leaky of old.

A new sidestand made of aluminium is slightly longer the ’07 model, and is now fitted directly to the instead of being braced by a It also features a larger foot to improve stability parked in tricky places.

The have EXCEL rims machined hubs and thinner and lighter spokes give unsprung masses.

All this the new EXCs vastly different to the models, and give them a different look and feel.

The all new XC4 on the 450 and 530 EXC-R models is the highlight for the range this year, as it is redesigned exclusively for enduro

The XC4’s state of the art design has electric and kick starters, with a six speed gearbox — all to last year’s model.

about where the similarities and the XC4 has been designed lighter, better power delivery and reliability. Both the 450 and 530 are similar in and every way, apart the displacement and gearing.

The 450 is a 449.3cc with a 95/63.4mm bore and while the 530 has a higher power thanks to a 510.4cc engine. Its and … is 95/72mm.

Both have totally new cylinder with one single overhead cam and valves in each. The valve have been increased, the valves are made of titanium and the angles have been for a compact combustion chamber.

also have weight-reduced arms with shims, and the cam serves as centrifuge for engine A slanted head cover makes valve access that previous models.

But does all that technical mean? Basically, it means the is more ideal for enduro while the reliability is better and it be easier to maintain.

Vibrations been decreased even so than the 2007 model, as a crankshaft operates a weight-optimised piston via a short con rod. also increases reliability the old model.

The counter balancer in the XC4 engine, which is powered by the features laterally fitted weights rotating outside the case and this also reduce vibration and gives friction because the rotating are external.

There are now two separate circuits for the combustion tract and to allow even more to the engine. There are also now pumps — two pressure pumps, one pump — and only one oil filter.

The FCR-MX 39mm carburettor acceleration pump and throttle sensor stays, as KTM says it better throttle response at than bigger versions on other brands.

Overall, the new XC4 is around half a kilo than last year’s, it is the most reliable and best ever from KTM.

The 250 remains much the same as year’s four valve, overhead cam RC4 engine, which is off of the 250 SX-F motocross model’s but has changes to tame it down to enduro riding.

The only changes for 2008 are that the train’s exhaust camshaft has new and optimised valve springs to it more responsive and have a power delivery. It’s designed to be more reliable. The change is a new ignition curve — changed to help the bike better at low rpm.

All of the four-strokes share the same exhaust silencer, that catalytic converters to meet III standards, while they are shaped to suit the bikes’ new design.

The frame used on the model EXCs has also a major redesign, with all inheriting a new chromoly frame massive oval lateral The frame is based off of the motocross of last year with changes, and it is designed to produce flex at the lowest possible The sub-frame is made of rigid profiles.

The cooling system is now in the frame’s triangle at the front of the meaning less tubes and cooling than last

The cast aluminium swingarm is out according to bending stress. It now more for improved comfort, a different mounting point for the WP PDS absorber gives a lot better, and progressive, feel in the rear.

The absorber is now more adjustable both high and low speed adjustments, and has 10mm more than last year due to its point on the swingarm. That means that the piston is higher. The shock body is now of aluminium.

It has a wider range for up to suit each rider, and a smoother ride.

48mm down WP forks are used and are adjustable, with an additional adjuster for 2008. They a new setting, again to help the riding comfort better, and like the shock, they a wider range of settings.

New protectors also wrap further and help to stop and other objects damaging the tube.

With all bikes very similar frames and KTM has found a base to work and has made it work extremely

I’ve almost completed a lap of the kilometre loop amongst the forest that has been out by KTM’s test riders. My is flowing, heart pumping, and I’m to really get the hang of this stuff. I carve through a left-hand turn and find splashing through a deep before I know it.

No worries what’s a bit of water hurt I carry on, and soon enough I myself on the bank of another crossing. This one is much

I do a double-take, before deciding to into gear, stand up, and ride on through.

Rubber tyres on slippery wet under water don’t well, but I make it through eventually coming to the end of the loop — soaking wet riding gear and to prove my experience as the first through.

The trails I’m riding, 150 kilometres north-west of Barcelona, are different than what I ever ridden in Australia and a real experience as I sample the and greatest 2008 model KTM EXC enduro range.

A 40 hour from Sydney (thanks to fights and lost baggage) was a experience, but as soon as I laid on the new EXCs I knew it would all be

They look sleek, and fast — very much to last year’s KTM SX motocross The plastics are minimal, especially at the end of the bikes, and the EXCs different to year’s models from to rear. The plastics are also and feature integrated stickers on the shrouds for minimal wear.

KTM has produced excellent enduro designed specifically for off-road use and riding, but the redesigned 2008 have been eagerly since spy photos surfaced in 2007.

The KTM 250 EXC-F

Leading the way for the company in Australian sales be the ultra popular four-… consisting of the 250 EXC-F, 450 EXC-R and the 530 EXC-R.

All three bikes are quite similar from a aspect, although the engines three vastly different when blasting around the The entire EXC range is based off of the SX motocross range, although changes are sprinkled throughout to them more rideable in the confines of riding in the bush.

spending almost two days in I just couldn’t wait to get out in the air and rip up some Spanish soil. The that we are riding features a variety of terrain including the water crossings, tight trails, and fire roads. of the downhills on the loop are frighteningly while the uphill climbs get more difficult as we rip up rocks and the dirt.

I was particularly excited to aboard the new 450 EXC-R. The 450 class the key players with over 10 in the class, meaning KTM would to really produce something to outshine the rest.

It is my first I climb aboard while in and straight away it is impressive. Its is typical KTM — very compact excellent quality components. The isn’t a whole heap to last year’s model, but were renowned as the best in the comfort-wise, so that’s actually a thing.

The hydraulically operated clutch can be with one finger (as with all and the gears shift seamlessly.

The out loop begins a little with quite open and plenty of fire trail, and really allows me to open up the and sample the power of the new XC4 engine.

I feel the extra zap off the bottom, and the feels a little bit livelier the former model. The engine a host of changes (see breakout), and it gives the KTM some personality in the bush. The SX (motocross) have always been for their power, while the EXC bikes are always much and more friendly.

The new 450 has more power throughout the rev range, but it does have the smoothness KTM is known for when riding in the

When really accelerating down the fire roads, it is the that is impressive as I bounce rocks and fight through the conditions. It keeps pulling as I get one of few opportunities to open it right up and the power.

I soon come a tighter section of the trail requires me to concentrate more and a little more precisely. It capably and is really easy to when I’m in between the narrow I never need to worry any stalling or any of the like, and that stands out when I need to at crawling speeds in squeezy or downhills.

The KTM 450 EXC-R

The Brembo also work a treat the hills, as the 260mm front offers good feel and power. The rear has a 220mm that doesn’t give as much feel, but still the job. The brakes are the same on all

Uphills are quite easy to do as the XC4 engine trots along, and gear is actually quite This allows me to use it in the difficult and not worry about stalling, second is a good option for things open slightly. I did get to use sixth on any section of the track as it was all tight.

While the new engine is and gives a little more to the 450 EXC-R’s ride, KTM has not forgotten the handling aspects of the new model. The designed frame is designed to while being the lowest weight, and this makes it and easier to steer than year’s model.

It handles well in both and open stuff, although it is to compare the overall feeling with the terrain and places we here in Australia. The new bike ever falter me though, and I it easy to manoeuvre around and up and over steep hills and The light weight of the new model helps me to last and not get too fatigued quite a bit of time on the bike.

The forks’ extra adjustability well too, as adjustments to the proved effective and gave I could actually feel. ride over bumps well, although in some they could be softer for my (68kg) to allow the bike to better over logs,

The shock absorber also has adjustment for 2008, and provided a situation as what I felt the front end. It wasn’t a huge problem and gave of feel that made the extremely rider friendly, going a little softer in the rate would improve it bit more.

After my experience on the I was really looking forward to the 530 EXC-R. The 530 is actually very in all ways to the 450 apart from the XC4 displacement, and that is largely to a higher …. The gearing is slightly taller on the 530 to help woe the power.

When you are sitting it feels much the same as the

Once the engine is running and you off, that all changes. though the chassis is much the as the 450, I got tired quicker the 530. The extra power it much more difficult to through the tight stuff, but it was a lot of fun in the open sections of the trail.

was also a ‘special test’ of track set up in a large open area and that’s where the 530 was the fun for me. I could use the power and click the gears, without having to man it through tight obstacles. If the areas around you are pretty open, then the 530 is a pretty choice.

It’s the best of the class enduro machines on the by far, although it just the correct riding areas to take advantage of its mighty On the other hand, if you’re a big you can take this beast and it will work well in tight and wide open areas.

The KTM 530 EXC-R

After wresting around the 530 for a while it was a huge relief to the 250 EXC-F as my final test of the day. I was feeling exhausted and the heat was getting to me, but the ease of the 250 revitalised me to have a good go

Again it feels strikingly to the other EXC models, but the light (it is claimed to be almost six kilograms than the 450 and 530) really a huge difference as soon as I’m along the trail.

I feel confident and aggressive on the trail, and admit, the smaller bikes my size and riding style. The of the bike allows me to place it I want to on the trail, and the light makes it handle just little bit better.

That always the case though, as at high speeds, the bigger and bikes tend to be more thanks to their extra In the tight enduro loop we have to ride in Spain, the 250 is the for me — especially when I’m so tired the heat and jetlag.

A 250cc is very user friendly, and one is a bit more lively than year’s — especially right off the It has that little bit more although it still doesn’t the punch of the Honda CRF250X bike.

You can’t argue the useability of the 250 EXC-F though, as KTM has the same smoothness that the model was renowned for. It has that bit more excitement

KTM knows how to make enduro and with a solid line up of for 2008, the Austrian company just regain that dominance of off-road weapons it enjoyed just a few short ago. The orange army is and ready for battle.
