It's easier to buy light than it is to earn it!

Not trying to high jack your thread. One day my wife asks me what this $130 on our credit card was, I tell her that it was for a new light weight Li-Fe-PO4 battery for the bike, and how cool it is and that it saved over kilogram of weight off the bike. She looks down at my waist, smirks and walks off without saying a word.

Most of what is on that list are not lightweight parts. In fact, the only part thing on it that is purely a weightsaver is that battery, which many are not immune to (ahem). Most of what came of this is how little weight you can remove.

Really, this has been a fun project. An early mentor of mine drilled it into me that I should know how to work on, set up, and maintain my bikes. Plus, with all the time I spend at a CRT, it is nice to play with mechanical things. But to each, their own.

Didn't mean to imply the project wasn't worthwhile just that we also need to consider the human elements as well. Gawd, I'd hate to justify some of my projects over the years!

Phil, not a problem at all!! I could use some lightening myself, but that would require drastic measures, like giving up our fine local micros....no way!!

The thing is this: the XR600R weighs 276 lbs and is a very solid platform for off road, DS, whatever. Before the 525 or 530, it was The bike for what we do.

The XRL is the same basic bike, but has been larded up 60 lbs. The e-start is worth keeping, but some of the stuff is absurd. It's not like a pure dirt bike, but is sold in street trim. For Pete's sake, the bike has passenger pegs, a helmet lock, and a decorative seat strap! For any off road use, weight loss is enormously beneficial. It is not like a bicycle where you buy pricey high end parts, it just takes common sense. This just separates the BS from the actual #s.

Edit: besides.....after looking at the MSRP of a 530, I would say some of us are cut from the same cloth, just in a less DIY way....

I always like bike weight threads because I learn real world weights, not published numbers. Also it's interesting to me that the te610 690r and the xrl are very close in weight. It seems that at this point makers can't produce a 650ish dualsport bike with e start that is under 300 lbs even in the upper price range.

That is true, but....the modern bikes all carry their weight much more centrally. They also have lower motor weights, lighter rotating masses, and more weight in more rigid frames and better suspension components. This is the biggest disadvantage of older designs, and cannot be overcome.

After riding my friends (ya, I have some) xrl my biggest complaint was the width more than the weight.

All very good points, having ridden a 690 I can say it feels lighter than it is, and much more stable than a xrl. The xrl represents the best do it all dual sport in the cheap category.

"Tail light saves 3 pounds alone..."

More myths to break: I have heard that the tail light weighs 5+ lbs, that an aftermarket silencer saves weight, and that the CRF conversion drops pounds too. All are untrue:




Tail light assembly: 1.46 lbs
Stock upper triple: 1.7 lbs
Stock silencer: 7.28 lbs

That huge tail light weighs next to nothing. A Q4 silencer saves less than half a pound. That stock triple is really light, and I doubt an RSW saves much - if any.

This is becoming an analysis of how to not ADD weight on. It is easy to strip 10 lbs of junk off the L. Trouble is, a skidplate, handguards, graphics, and some better tools add it right back on. Netting less weight is possible, but a lot harder than you would imagine. And the next time I hear that exhaust saves 3 lbs or the tail light weighs 5 lbs alone, I will laugh.

The key things at this point are the smog stuff, and the wheels. My guess is that the CRF wheel saves weight because of the alum axles and spacers, but that an HD tube and Dunlop 606 add more back on.

xrl hubs are alumium too right?
