Best DT1/RT1 weight savings

[Iain Cameron]

You could always go for the Jones titanium frame . Hollow axles , drill everything that you can get to . tyres and tubes vary a great amount . Go the lightest spokes with alloy nipples . Iain 
ps If by any chance in hell you get a Jones frame I know a DT\RT tragic that wants one as well .

there were only four of those frames made, right?  I'll see if I can find two of them. 

Got to use stock frame, swingarm, triples, forks and hubs. 

That leaves bolts, rims, spokes, axles, backing plates, brake arms, sprocket, levers, handlebars, pipe, tires, tubes, seat base, fenders and tank as the items that can be lightened. The skid plate, oil pump, oil tank, air-box and steering stabilizer have all been removed.  I'm running a Hooker pipe, Renthal bars, lightweight controls (levers, throttle), plastic fenders and an aluminum sprocket. I'm adding Excel rims and HD spokes, which should drop the wheel weight by 1.25 lbs per wheel. Aluminum, titanium and the drill could reduce weight a little more.

You also need one of my trick billet clutch actuator/sprocket cover with a light clutch pull. I'll get Firko to put a pickie up....he has 2. I you can get hold of a YZB clutch cover and ignition cover, they are magnesium. Hollow chrome moly axles are easy to make, are stronger and are waaay lighter.

Someone told me nitrogen is lighter than air! May I also assume you are doing everything to reduce your personal mass including voiding you bladder and bowels before a race. Also consider shaving your body. Every bit helps! Cheers Jerry:)

Thanks Jerry!  I forgot about the rider.  I could drop twenty pounds a lot cheaper than the RT-1 could. 

'80's style nylon pants, a carbon fiber helmet and weigh all the boots at my local bike shop to get the lightest pair, It's about the total package (rider and bike).  Is oxygenated fuel lighter? Still and aluminum DT-1/RT-1 style tank and a true chromoly swingarm that looked exactly like the stock one would be super cool. LOL

Heh heh I've been trying to trim some fat from my boat tail Bultaco and then I walked in front of the mirror, 10 kg off the bike and I would make a potentially competitive package. ):J
