I weighed my bike...

39 posts in this topic

I weighed my bike on a small digital freight scale.  Freshly washed, not totally dry, 95% clean.  Didn't drop the skid plate.   1/2 tank of fuel from my last ride.  My Jerry can was empty.

 

Front wheel : 119.5 pounds

Rear wheel: 123.8 pounds

Total 143.3 pounds.  Call it 250 pounds full of fuel.  

 

My bike is equipped with a 130 IRC M5B in the back and a IRC Vulan Enduro 35E in the front.  As well as heavier springs, front and rear.

 

This weight almost exactly matches the weight calculations I've been doing all along in this thread.

That would be one awesome machine if it had the same features from stock but weight 250#.

I ride my trials bike for awhile and jump on the 450.  It feels like a chopper after that.

That's quite a weight savings. Makes my bike seem like a total pig. I know my brakes are heavier and suspect the wheels/tires are as well... and stock exhaust doesn't help, that's the easiest place to drop weight.

Your stock wheels are some of the lightest available.

Your brakes (you mean the calipers?) might be heavier than Brembos, but they never overheat or flex.

If you mean the discs, yes, they are Carbon steel, not hi-tensile steel, and thats why the don't overheat or groove.

 

The majority of the weight of the WR is sestemic to the entire design: robust and long lasting, not light and flexy.

 

If you could get a few parts made fore the WR to mimic the precision light weight parts on a KTM, you could loose a lot more weight and not 'remove' anything to do so.

 

....but, then the WR would cost $10,250 OTD like a KTM, not $7,400.00..........

 

I would love to see aftermarket companies making these parts, but let's face it; there is no market, and it's just not that important:

Hollow axles

Alloy kick stand

Alloy fastener kit for all non-structural compents

Smaller fasteners kit (major size fasteners)

Wiring harness made with much smaller wire (like KTM)

Clutch hubs turned and drilled 

Shift drum copied out of 7000 series aluminum

Smaller Stator

 

...that would take about another 13lbs off, even before going with Ti parts.

 

Or, you could just not fill up your gas tank all the way when you go on a 50 mile ride, and there you have a free and signifigant weight savings..........

If you look in my sig, you'll see I specify "Supermoto". Excel /Talon 17" wheels, street tires, 320mm rotor, 4pot Braking caliper. When I threw it on a scale with half a tank I think I got 273lb. The only weight savings that I've done are a Shorai and a YZ style rear fender. Of course, it's for a different purpose.

I agree with Krannie that the WRs are very durable bikes.  I'm coming up on 2 years of woods riding with mine and not a single failure or breakdown, except when a hydraulic clutch line came loose.  Stock clutch, rads (with no rad guards !) hubs, plastic, etc.  Its all going strong.   Not even a rip in the seat.   And I've dropped my bike a lot.  Change the oil and go.

Hmmm, Hyrdro clutch ??

Yep.  Replaced the clutch cable setup with a Magura hydraulic unit.   I'm strong enough that the stock clutch pull was OK, but the pull and feel of the Magura is excellent.   These bikes should come with it stock.

I modified my clutch basket and hub (swiss cheese mod) and changed to an ARC lever, and now the feel is  better and lighter than my KTM hydro........

That is really interesting. Link ?  Pics ?

 

BTW, I might make it to your neck of the woods err... desert in early 2016.  I'd love to ride.  I know nothing about desert riding though.

Whoopie

 

I agree with that sentiment.  I posted this because certain people were calling me out about not weighing my bike.  I don't care what the scale says, I care about how it handles.

There was another poster who went into some detail about the mod.

 

My buddy Paul at AS Racing took the info and made a more scientific approach to the whole process, adding about 40 small holes to the basket and hub.

 

Paul has choosen not to share the details for free.........

 

The ARC lever is actually a lower leverage (which accounts for a lot of the lighter pull) and now that the discs separate much more freely, I can shorten the lever throw.

 

Now it feels like there is only two springs in there, and it disengages in 10mm of lever throgh as much as it used to disengage with 25mm.

Well, we go into the desert anytime it rains, or in the winter when it's under 80 degrees.

The Desert is about covering miles. 80 miles in 3 hours no problem, with mostly all standing-up riding. Not straight, not flat, not boring either.

 

The thing about SoCal is the diversity. 

 

You can duplicate just about any riding condition nation wide in a 3 hour or less drive from LA.  

 

Especially the epic man-crushing single track, or the senic flowing single track. 

I like the fact that in 30 min from walking out of my garage I can load up, drive, unload and be suiting up, and riding some of the most fun terrain I've ever ridden.

I've got a 14 wr, when I first started riding I was planning on doing trails but now I jus ride track, I love jumps, I've stripped everything off my wr to make it better for track, still have kickstand ( it's really handy ), electric starter ( I could prob lose this but not sure if it's worth the weight I will lose), I've had the suspension tuned, two brothers exhaust , sprockets, levers, bars, remapped. My question is... Should I swap it for a mx bike or jus strip some more weight off this bike, I got a fella with a rmz 450 2014 that wants to swap, I love the wr and I've done so much to it so it's hard to part with, I also think the wr engine would last longer,can the wr be made into a reliable motocross bike? I'm hittin pretty big jumps, up to 100', but thinking I could benefit from a lighter bike. I'm not racing, jus with mates every wkd.

Whys that?

Why is that

Why's that

 

It is common knowledge that Suzuki products are in general not up to the standards of other motorcycles.

Brittle bolts, hubs, cases, weak stators, stiff transmissions, very weak clutch and transmisson, etc etc etc.

Gee sorry I forgot an apostrophe.... Thanks for the grammar lesson though.

Putting the rm aside, do you think the wr could be made into a decent mxer.

You already have a thread covering that
