I dont like the speedbrain look. it also looks unfinished and the tank is too high. The fuel should be lower, in the gap between the fairing and the bashplate. That gap looks unfinished to me. And that gap is exactly where you want to be storing fuel - right next to the centre of mass for the bike, and lower than where the centre of fuel mass in the speedbrain version.

If I was going to move from my current not finished look, it would be to put in rally tanks, but making the molds for them is super expensive and a mold maker is not among my list of friends and contacts..



I dont really like what they did in repositioning the KTM designed front fairing. I assumed KTM put a lot of effort into the positioning of the 450 / 690 front fairing. I spent a huge amount of time with Erik at Hot Rod to ensure we replocated the position of it on the bike. And I tell you what, it works really really well. Its small, but super effective. Speedbrain have copied it, but moved it lower and closer to the rider. I have no doubt its less effective in that position. Speedbrain have prioritised compactness, but they will surely have sacrificed effectiveness to do that. I also doubt speedbrain ever did any specific windtesting to test the effectiveness of the fairing position in reducing wind on the rider, whereas I am sure KTM did, or at a minimum had it all worked out in the design drawings - because as mentioned, its very effective.

This was probably the most unproductive day at the office ever. Read the whole thread. Awesome thanks for sharing.

My favorite script of trailer. "you go first.... no there would be dust in the camera." "I had been driving very slow before I met you guys." Can't wait to see it all

Steve was a very fast learner. He went from almost no off road experience at all (just a few days in Tajikistan) to 140 km/h (85 mph) on the dirt, -as per the speedo in the clip - in 3 days.

Walter,

Have you any idea what was the weight of your XChallenge 2012 setup without luggage?
I am just interested how much the fairing, aux tank etc put you back weightwise.

bashplate - 4 kgs
steel subframe - 3 kgs extra
aux tank - 2 kgs
shock & coil - approx extra 2-3 kgs
front subframe - 1.4 kgs including neck brackets
front fairing - hmmm dont know, but I would guess 2-3 kgs.
rear rack - 4 kgs

Thats about + 17 kgs

Pretty much everything else is an even swap ... hubs, rims, fenders, forks seat etc will all weight about the same as stock. Maybe the front hub and rear sprocket save a small amount of weight - not to mention my 7075 gold engine bolts replacing the steel ones. Maybe I save a 0.5 kilo on some of those things combnined ... then save over 2.5 kgs on the lithium battery ... dont know how much the OEM bashplate weighs ... but there is a fair bit of plastic I no longer have - everything from the chain guard to oil tank cover, to front mini fairing, to bits of the side panels. Maybe there is an extra kg of plastic and oem bashplate that has been discarded too in various places on the bike.

so if I had to guess, net approx +13 kgs vs showroom weight

Having just bought Phil's RBA (Rebadged Aprilia: I struggle to mention the Bayrische Motoren Werke acronym... ), it looks like I have some reading to do, although looking at the index/summary in post #1 most of it has already been done on the bike. It just needs some post trip TLC when it arrives back in Europe.

Many thanks for taking the time to start and update this thread.

Dakar rims are aluminium.

There's usually not a huge weight difference between stock alloy and excel rims (if they are the same size), aluminium in most grades is about the same density, it's just that the grade used in the Excel rims is better.
