Yeah, my 'box of parts I've removed' weighs in at 73 pounds, as that's the only real measuring function I have right now. =) My Scrambler weighed in at about 494 dry, is the only real info I have on those regards. I should weigh it over at Evo Motorsports down the road again. Were your triples not alloy from the factory..? Mine are, but they're cast, not CNCed or anything.

I was surprised at the weight of the stock shocks and front fork, though. I saved a bunch on that side.

Perhaps the exhaust, as well, with it's plethora of heatshields accounts for some difference.

What's the weight of your wheels and your new tank? And what's the capacity on the tank? I want a better range, but EFI tanks don't really exist easily found. So I'll probably have to customize it no matter what.

I'm wondering what all on the Thrux might be lighter from the factory! The engine weighs a frigging ton, though. Good lord.

Anyway, I'm just rambling now. =) Thinking about it now, I probably replaced the 73 pounds of goo with 20ish pounds.

Wheels next! Gotta keep the eyes on the prize, the lower unsprung weight.

But also lighter wheels, alloy tank, alloy fenders, cut the frame, alloy triple trees, alloy swingarm, motodaget chronoclassic etc. Even stripped off the paint for a few pounds and nickle plated the frame.

Its tough to lose 80 lbs on the bike. And expensive ;-). I'm 170 lbs and 6" 1', so its not like I'm packing extra on my frame. There wasn't anything to gain from dieting for me !

You can find 'em here: http://knlcycle.homelinux.com/scrambler.htm

Rear pegs, I recommend grabbing some track ones of the right dimensions and just swapping those, if you wanna keep them.

As far as the footpeg attachment points, you'll either want to keep them as they are if you do anything offroady (The Bonnie ones have had some instances of falling apart) or are hefty. I've not really approached that particular 'issue.'

As far as 'bitubo on front,' my front forks have Bitubo inserts like this:

What is "bitubo on front?"

Any idea how to lighten the massive casting the footpegs attach to?

Rear pegs weigh a ton as well, along with the triangle attached to frame. No idea how to address that; I do need them.

those foot pegs are sexy

any comparison in size next to a stock bonneville peg, i would love to see that

casida · 11-14-2012, 11:58 PM

I could probably arrange that, sure. I'll check in tomorrow-ish with one.

nametzj · 11-15-2012, 03:36 AM

Thank you , Eddie those footpegs I will buy!

Has anyone found a better kickstand for the scrambler? Stock leans too far, and weighs a ton as well.

Forgot to say. I put intiminators, about $180, in forks. Much improved in the rocks and far better control in turns on rough roads, both. No weight savings though gotta go after rear shocks next. Stockers not good, specially with that heavy wheel. Shocks probably more important than a lighter wheel for handling/control improvement? Similar cost factor I think.

+1 on the heavy box of bits i've stripped off- but the quickest way i found my bonneville to be light was when my wife bought an america......my bonnie felt anorexic after heaving that lump around!!!!!!!

its part of the look of the engine case, i know there are stainless bolt kits available, but they don't do much, if anything for weight.

when i rode road bicycles, every fastener would be titanium, while it is expensive, and not necessarily the strongest bolt material, changing all the engine cover bolts to titanium bolt would save probably close to 10 lbs.

sometimes good deals for Ti hardware can be had on ebay, its just a matter of figuring out what sizes are necessary.

Pro-Bolt have engine bolt kits instainless, titanium and aluminium. If I remember correctly,the ti set will save you about 150 grams, while the alu set will save you about 250 grams (stock set being a tad more than 400 grams). Not a lot, but if it is one of many items changed or dropped then it will contribute.

I'm old and can't remember all the numbers. But I did document it all here http://www.triumphrat.net/twins-tech...build-log.html

Warning it's 27 pages. The triple clamps may be in a different thread, so search for my name and "triple clamps".

Yeah, the engine weighs about 200 lbs. I had to lift it on to the pallet when I shipped it to TPUSA and lift if off and onto the motorcycle stand when it came back. And then I did some head and jug work twice after that. Not much we can do about that lump of steel.

My triples were alloy in top, but cast steel ont he bottom and even the centre tube was very heavy steel. The DeCaeser triple clamp was a lot lighter. Again, numbers are in my build thread.

That method is only somewhat accurate since there is weight differential to account for on things like exhaust, shocks, etc...

So you need to make sure to subtract the weight of the stuff you put back ON the bike! Best way is to go to a scale large enough to roll the beast on...
