New Race Build For 2024

Aprilia Tuareg 660 race build. The team has spent many hours over the last 18 months with the many new twin parallel machines available. Some went with the Tenere but Howard and Chris preferred the Aprilia.


The aim as always is to make a competitive race bike without spending 1,000's.

The first thing is the complete removal of ABS, then add an Enduro wheel set. We will be experimenting with KTM wheels and custom spacers. The ABS rings will be a complication but we can machine up our own if needed. The measurements taken indicate the front is very likely to work but the rear a little more tricky. Would be good for us as we collectively have many KTM 990, 950, 690 and EXC wheels knocking about. Maybe we end up machining a new hub?

Suspension, we need to add 20mm, stiffen and then modify and strengthen the tower to take the Nav gear needed for racing. The suspension as standard is actually really rather good. It really takes some pushing to feel the limitations. They did a really good job.

The usual bash plate, aftermarket exhaust will be added (there's plenty to choose from now) and then add a steering damper. The great thing about this motorcycle is that it's the same motor and electronics found in the Tuono which means there are pages of aftermarket mods.

We will update on our Facebook page and on our YouTube channel on the build. We have 3 months until the 1st rally of the season in Morocco. Not sure we will make it but we will try. The suspension will be the biggest hurdle.

Chris also has a plan B to just completely swap the front end (using a modified triple clamp) for a 990 S. We will see what happens!

New Video Series - From Wreck To Rally

 

So, we have been on hiatus for some 6 months paying off debts and getting ready for some events taking place at the end of the year.


AJ had to get a new wiring loom built and had other issues with his bike. The whole wiring loom thing became a real mission. Quotes were over £1,500 and then the guy AJ went with produced a loom full of issues. From here on we are just going to use original wiring looms and rebuild as we have done in the past.


Chris has had 6 months recovering from the eco race. He got covid twice and had trouble with fatigue and breathing during 2022. Just before the event he got another chest infection and the rally was done on a diet of steroids and antibiotics. With a 3rd bout of covid and the exhaustion of the race after it took a while to recover.


Howard and Ian took part in the Illyria raid in May. Howard took the new Aprilia Tuareg and thoroughly tested it. We will have a video of the event and our thought on the Tuareg later on this channel.


Tim (@fatrally) got his rear race tanks fitted and raced in Wales but managed to snap his 950's cam chain so has been off the road fixing that. 


And Eric went to Morocco and did his 1st desert race (Tuareg Rallye).


So this series is basically a complete rebuild of a 2004 KTM 950S which really is in a sorry state. It's a classic bike and absolutely deserves a new lease of life. The bike is going to be stripped down, completely repainted, put back together and modified as a race bike with the following parts:


 - Aurora Superlight race tower with MD roadbook and ICO trip meter.

 - Wiring will be modified to run with no oem clock but lights and gauges for oil pressure, temp, low fuel, etc.

- Custom rear fuel tank built into the subframe.

- Scotts Steering Damper and Sub Mount (already on the bike)

- TrpleClampMoto foam filter for the intake

- Wheels re-laced for 2.5 and 1.85 rims

- Custom radiator by GMX

- Rear tail tidy (haven't decided which one)

- 265mm Suspension

- Single Disc conversion

- Carbon bash plate which you can find out about here: https://youtu.be/GBEcEz1w-0c

- Facet Fuel Pump

- Fuel Regulator

- Unit 31 Graphics and fuel pump adapter plate. https://www.unit-31.co.uk

- KTM EXC fender and adapter bracket by Polisport

Africa Eco Race 2022 KTM 990 Parts and Gear Review

So the 16 year old KTM 950 Adventure got to the finish line of the Africa Eco Race in the Malle Moto class with Corky at the helm, and before it heads off to its new home there were a few items that were new to both the rider and bike that we'd like to share with others. These items were definitely paramount to the success of the bike and rider reaching the chequered flag in Dakar.



1) Unit 31 Navigation Tower And Screen (https://www.unit-31.co.uk/shop/4):

There were quite a few crashes as expected in a rally of this kind with the biggest being right at the end during a whoop section sending the rider flying and bending the bars and Iritrack bracket. 


The tower survived unscathed and because of its welded construction nothing rattled loose, moved or broke. The screen did get bent and weakend at the top section but as can be seen from the photos above and below it held together and nothing broke off.




2) SBS Carbon Clutch Plates And Steels (https://www.unit-31.co.uk/shop/4):

Chris and AJ have been using SBS brake pads for a while now and are very happy with the performance. We recently discovered they did clutch plates for the LC8 and what a find they are. No fade, no wear and the oil wasn’t contaminated when changed at the half way point. Without doubt the OEM fibre plates would have disintegrated in the deep soft dunes of Mauritania. We know this from past experiences. Sitting at the bottom of a 2 story dune in 2nd gear, fully opening the throttle and letting the clutch out quickly would have destroyed other plates. 


Chris used a heavier set of clutch springs from Barnet just to be sure of good contact and lessen the chance of slippage.


3) Metzeler MC360 Med/Hard Rear Tyre (www.metzeler.com):

Chris and Andy couldn't find their usual Pirelli XC Scorpion in time for the race and very kindly Metzeler UK suggested the MC360 Med/Hard. At the time it wasn't an ideal situation and there was a lot of concern, but it was all thats was available at the time.




There was no need to worry - the tyre worked perfectly in the desert conditions. Paired up with the Michelin Desert mouse it was a great combo. When the 1st tyre change was done during the rest day the mousse although starting to go soft had no other damage and could have been used further. 


The Metzeler tyre still had plenty of tread and importantly there was no chunking. In the above photo the last tyre fitted during the rally had done around 2,000 km's. The tread pattern hooked up great in the sand and there were no complaints in the rocky and fast piste sections. Now the tyre of choice for desert racing and we will test to see how it performs in European rallies and on the UK trails.


 4) Giant Loop Pronghorn Straps & Armadillo Gas Bag (Giant Loop):

Saved Chris and others loads of times when extra fuel was needed. Was also used many times to transfer fuel from one bike to another. Packs up small and is very lite when not in use so no excuse not to carry around with you. 


Tough as nails, simple and does what it says on the tin (as with all Giant loop products) and now Chris won’t leave home without one. Pronghorn straps were great and quick to use. Coolant and water bottles were strapped to the back many times and never was anything lost to the desert. The rubber construction of the straps helps grip and keep everything in place. 


5) Tripleclamp Moto Airfilter System (tripleclampmoto):

Chris used the new plate which has a guard up front where the majority of the dirt and dust would hit the filter. This used along with the new dust filter skins was a great combo. Yes, there is more power with an open air box but just as importantly there was no crud in the carbs during the event.


Just 4 pre oiled filters were used during the 2 week race. The days included plenty of sand, mud and a water crossing with many hours riding each day in the dust clouds of other vehicles. The air filter kept it all out. The other bonus is the fact the filters pack really small which is important when the rider needs to live out of two metal boxes for the duration of the race.



6) Kodama Carbon Bash Plate (www.kodamacomposites):

This is a project we worked on alongside bike carbon specialists Kodama Composites. We had a very rough shape/prototype and spent 2021/22 perfecting the design and testing. Maximum protection, light and again survived the rally with no issues.


As the custom oil tank was situated at the front and low down along with the fuel pump it was very important it had good protection. Thank you to Chris and his team for a bash plate fit for purpose.

7) Klim Dakar Jacket used with Alpinestars Bionic Chest Protector (Unit 31 Klim Dakar):


Chris used an Alpinestars Chest/Back Protector with the 3DO armour in the elbows and sleeves of the Dakar jacket, Both jacket and armour protected the rider and survived the crashes. The jacket/armour combo made the extreme heat in Mauritania very manageable and Chris will never go back to using a race jersey. 



The vents allow for temperature control, there is more abrasive protection, pockets for food, spare gloves, etc and generally the rider is more comfortable. We knew the gear was good as we've been using the Dakar jacket and pants in the UK for racing and trail riding but turns out it also workes great in the desert. 
Jacket and pants came home, went in the washing machine and not a tear, broken zip or other damage - perfect.
