2012 undoubtedly was a very successful year for KTM’s road-racing department as they took the top 4 places in the Moto 3 category.

As a MotoGP fan, naturally I was interested in their race winning 250 cc Moto3 bike. However, after reading more about the bike and KTM’s involvement in road racing, I realised that this was actually not KTM’s first attempt into MotoGP racing!

Based on what I’ve found out, I’ve written an article about KTM in road racing, their successful Moto3 bike and their new production racer, the RC 250 R.  Hope you’ll enjoy reading it!

First Attempt

It may seem that KTM had a fairy tale start in the 2012 MotoGP World Championship – a first year ‘rookie’ constructor that ends up taking the top 4 places in the Moto3 category.

However, this is not completely true, for KTM have endured their share of setbacks in earlier years.

Their first foray into MotoGP was in actually 2005. At the time, KTM entered into an arrangement with Kenny Robert’s Team Roberts as an engine supplier.

Team Roberts had initially developed their own engine, the KR 5, in 2002 with Proton funding, but soon realised that it was not going to be competitive against the dominant Japanese factory teams at the time, it made only 185 hp compared to 240 for the competition.

Looking to improve their competitiveness, they thus sought a partnership with KTM to develop an engine to replace the KR5.   Things started promisingly, with the KTM V4 indeed faster than the KR5.  However, when the season started, it soon became clear that the V4 was still not good enough.   Mid-way through the season after only 10 races, with no results materialising, KTM withdrew their support.

The split between KTM and Team Roberts was acrimonious, with Kenny Roberts claiming that KTM ‘breached their MotoGP commitment

Thomas Felber, the man leading the V4 development at the time, admits that that was a difficult time then. While the V4 made good power and was rideable, there wasn’t enough time and electronics to make it fully competitive. ‘Maybe we entered MotoGP too soon’ he says.

However, it wasn’t a completely a wasted effort. Everything they learnt about building their V4 proved immensely useful in building their Moto3 winning bike.

Re-entry in 2012

In 2011, after a six year hiatus, KTM signalled a return to MotoGP racing by entering the Moto3 class for the 2012 season.

Not content with merely playing a support role, this time they chose to go the whole way by entering as a factory team. They kept everything in-house, developing the engine and chassis completely at the headquarters in Mattighofen.

On a separate programme, however, KTM provided engines to German chassis manufacturer KALEX to run, in parallel, an additional KALEX KTM Racing Team.

The path of in-house development worked, with KTM’s results in Moto3 being completely opposite to their ill-fated 2005 foray into MotoGP.

When the 2012 Moto3 season ended, the top 4 positions were occupied by KTM riders.

2012 Moto3 bike

The race-winning KTM Moto3 is nothing short of an engineering marvel.

The 250 cc engine is highly over-square with a 81 mm bore and a 48.5 mm stroke. It revs to 13,800 rpm and makes 54 hp at the limit.  At just 25 kg (55lbs) dry, you could say it is feather weight.

250cc, 25 kg, 54 hp!

The chassis comprises of a a steel trellis frame with an under-braced aluminium swing arm, a carbon fibre self-supporting rear subframe and a seat unit are bolted to it. The headstock and swingarm positions are adjustable for tuning the chassis to specific track requirements.

The fairing of the bike was designed using Computational Fluid Dynamics (CFD).  Using sophisticated computer algorithms to predict how air would flow over the bike, KTM started improving the aerodynamics of the bike even before a single piece of carbon fibre was laid.

Following CFD, the bike was then physically tested in Dallara’s windtunnel in Italy. The lift-drag ratio was fine tuned there.  See the small tail-piece to keep air flowing smoothly? That was completely determined by wind-tunnel testing.

2013 production racer – RC 250 R

Following their 2012 success, for 2013 KTM is developing a production racer of the Moto 3 bike – the RC 250 R.

A production racer is a motorbike made specifically for the track racing, but can be bought direct from the manufacturer to be raced ‘out of the box’.   For US $54,000, customer teams and other ambitious privateers will be able to purchase this bike for races in 250 cc 4-stroke classes.

While certainly not cheap, the RC 250 R is essentially similar to the Moto3 bike.  In fact, all the Moto3 components be purchased separately and fitted on the production racer, making it identical.

Say’s KTM’s Head of Road Racing, Wolfgang Felber:

‘The basis of the Production Racer is not much different to our Grand Prix motorcycle. The GP bike is only adapted to suit the current Moto3 regulations’ for example it runs with the regulation Dell’Orto electronics unit, has a maximum of 14,000 revolutions and has an Akrapovic exhaust system that allows 115 dB. OZ magnesium wheels, a factory braking system with dual brake disks from Brembo in the front and WP Suspension elements all save weight – but basically these are also components that can all be fitted to the RC 250 R Production Racer!”

Specification wise, the production racer has a slightly lower power output of 49.6 hp at 13,500 (vs 54 at 14,000 for Moto 3). Front and rear Suspension is provided by WP and completely adjustable with 20 settings each.  Wheels are forged aluminium instead of magnesium. Dry weight is 82 kg (181 lbs).

Complete specs for the KTM RC 250 R production racer can be found here.

So there you go, a look at KTM’s initial unsuccessful attempt at road-racing, followed by later success and how their building on their success with the RC 250 R.  I hope you enjoyed reading my article.

2012 KTM 690 Duke vs 2013 KTM 690 Duke R

Difference between 2012 KTM 690 and 2013 690 R

What are the differences between both bikes?

Good news for US KTM fans! Cycleworld has reported that the 2013 690 Duke will be arriving on US shores.

The 2013 690 Duke has some minor mods over the 2012 model, but the more exciting stuff is that I’m guessing the hotter KTM 690 Duke R will follow shortly after. (Fingers crossed)

The 690 Duke R is based on the bike that was used in the 2012 European Junior Cup race, so it’s verified HOT. (Though Honda has replaced KTM this year).

So what exactly are the differences between the 2012 690 Duke and the 2013 690 Duke R?

Be unsure no more, I have created a 1-pager that captures everything neatly for you.   Enjoy it, share it and comments always welcome! :)

KTM Adventure 1190 Link Summary

KTM 1190 Adventure

KTM 1190 Adventure

With the KTM 1190 Adventure getting good reviews on the motorcycle sites (here and here), it’s safe to say the bike’s launch has been a success.

It has gotten a lot of coverage and this has resulted in many articles floating around, so I’ve tried to gather and categorise them into one place for easier reading and reference.

Enjoy what I’ve put together and please share this KTM Adventure 1190 link summary page with anyone who might be interested in buying the bike! ;)

Ride Reviews

Here is a collection of the ride reviews by the motorcycle sites that I usually frequent.

Key points about written about the Adventure 1190 are an agile chassis, great power–to-weight ratio, effective (read: unobtrusive) electronics and aggressive looks.

All good then.

Differences between Adventure and Adventure R

Visordown go one step further and write a great one-pager explaining the differences between the Adventure and the Adventure R.

Basically, the R is more off-road focused compared to the non-R model.   So what do you get for the R model?

Bigger wheels,  longer suspension travel, a higher seat, lighter weight and crash bars as standard.  Oh, and it’s also more expensive by £600.

Launch articles

The KTM blog gave a great very detailed look into the launch that took place in Tenerife, Spain from 28 Jan to 8 Feb.  All the first-ride reviews you read above were probably experienced here!

Day 1 : KTM communications manager Thomas Kuttruf arrives ahead of the journalists for prep.

Day 2 : Thomas scouts Tenerife and rides the routes ahead of time.

Day 3 : Day before launch. KTM staff set up the press area.

Day 4 : Start of launch and journalists and other KTM staff arrive.

Day 5 : 1st day of riding. SportmotorradmagazinMotorcyclist and Cycle World give first impressions of the bike.
(All good feedback expectedly! haha)

Day 6 : 3 time Dakar winner Marc Coma joins the party!

Day 7 : Thomas leads a fast group including Marc out on the roads. More first impression quotes.

Day 8 :  Detailed interview of Simon Weir (RiDE magazine) posted.

Day 9 : Third group of journalists ride the bike.  Questions regarding bike development answered. FYI, it took 130,000 man-hours to build.

Day 10 : Final riding day.  5 time Dakar winner Cyril Despres on site!

Day 11 : An hour-by-hour (6:30 am to 1:19 am!!) peek into a typical day at the launch. Hectic is the word.

Day 12 :  Final day on Tenerife. All KTM personnel involved are listed (18 in total)

Pre-launch articles and videos (late 2012)

These are a collection of the videos and pre-launch articles when the bike was first introduced to public in late 2012.

If you’re going to buy the bike, watch and re-read to convince yourself that you have made the right decision to buy. Ha ha.

Video : Worth watching because the MCN guys actually rode a P3 late prototype bike BEFORE the official launch.

Video : Official KTM video (cheesy soundtrack though)

Video : KTM launch the bike at Intermot 2012

Video : Lots of close-up video shots taken of the Adventure R at a bike expo. (Guy doesn’t sound very convincing though, he says ‘big bore adventure bike’)
