At 275 lbs I may have the lightest 650 around but the little XR is another 92 lbs lighter yet !!

You can see the swingarm stretch, relocated footpegs and 3.5 lb custom pipe in this last picture.

No kidding.... what are the mfg's thinking... this is the type of trail bike I want, and I am sure would be cheaper than a KTM freeride.

Not to mention, if you are basing the engine on the honda 200/230... A CRAP ton of cheap fairly reliable Chinese motors will bolt right in

Gronk, I'm pretty sure a stock 650r weighs more than 290? that's probably the dry weight and I can't find my notes but I thought it was 306 ish with all fluids and no gas. Everything contributes to the weight loss,.. lighter wheels, brakes, shock, swingarm, lighter headlight, etc,.. The missing airbox saves nearly 5 lbs and the missing shock linkage was another couple lbs. The better suspension makes a huge difference too, no swapping in the whoops and no shock fade.

Byron 555, the Freeride is not really very light and it has less suspension travel. There's another one called the Bergham R250 that is the same way. Hardly any lighter and less travel. They both have all the complication I don't want on the trail with fuel injection, e-start and water cooling. however they both validate the concept that less power is better if its the right kind of power. My little Powroll 218 stroker with torque cam is the friendliest, smoothest most ridable power I ever experienced. That was the biggest shocker, coming off a 650 I thought the 200 would be pretty lame but it will pull 6th gear in deep sand and hang right with a 450 in michigan trails. I may be using 80% of my power all the time but it still has more than I need! The 218 has about 30% more torque than stock and that feels like a lot more when you shed so much weight.

Building around the little XR motor means I can swap in many of the chinese clones as you pointed out but also the CRf230 engine with its e-start and available hop up parts. These old school engines may seem uninspiring but they respond well to hop ups and really wake up when installed in a radically lightened bike.

on a 500lb industrial digital scale

-2006 Husqvarna 610SM, no mirrors, new pipe, no bark busters, no passenger pegs, 3.2 gallons = 318lbs
-2007 Husqvarna 610TE, mirror, skid plate, no pegs, bark busters, small rack, 3.2 gallons = 325lbs
-2006 Yami WR450, plated, armored, bark busters, 3.4? gallons, Lighter tiny battery, GPS, small rack = 285lbs
-2009 Husky 450SMR, 2.2 gallons, no armor, mirrors= 283lbs
-1996 Honda XR400, armored, bark busters, no battery , 2.2 gallons, dirty = 280lbs
-2011 Huky 310TE, huge bark busters, skid plate, 2.1 gallons, GPS mounted, dirty = 264lbs

When I get time Ill throw a YZ426, DR200, and XR250 on there

I loved my 610s, but they felt every bit of the 60lbs more than teh 310. Was great above 30mph, but sucked in the woods and on top of me. 310 wont run 95mph down the interstate for an hour like the SM will.

Yes. Full of gas. Smallest was 310/ 400 probably 2.2. WR and 610 have 3.2ish. None were "big" tanks.

Suzuki now claims 377lbs full of gas for a stock DR650se,they usually dont add weight to their specs. The pre 96 DR was way heavier,I forget how much but they were even more of a tank.

Neat little 200,those footpegs being right down at the bottom of the frame work good in rocks/stumps and deep ruts? I would hate to turn my foot around backwards with those. Amazing its lighter then a 200KTM with that old school Honda engine,or even lighter then the newest trickest 2 stroke 125 made.

Back in 1982 I took a Suzuki RM125 chassis and put a Honday XR200 engine in it. With 1 gal. of gas it weighted 198 lb. It routinely got 100 mpg on PNW single track trails. The manfufactures haven't improved since then.

Cool thread. I think the bathroom scale method works well if you use a short 2x6 to distribute the weight of the bike on the scale and block up the other tire to same height.

TE630. Skid, barkbusters, windshield, gps, rack, no luggage, no fuel, no Givi = 340 lbs.
6.6 gal fuel and normal luggage load (bags,Givi,tools,etc) = 410 lbs.
47 rear wheel hp

The weight of the TCI Outback rack was almost exactly offset by the 14lb weight loss going to FMF exhaust.

It has a Powroll stroker 218 motor, MX suspension and brakes and is street legal. It can embarass pretty much anything in the tight woods and with the 6 speed wide ratio trans will cruise 55 without stress. I think its the best bike Honda never built. Ironicly its 95% stock Honda parts bolted to a custom frame, something Honda could have easily done.

This bike need it's own thread!

The low tech/ low weight concept makes total sense to me. I'd much rather have something along these lines than something with a on-the edge motor, water-cooled, etc.& all the extra junk that goes with it.

I'll be interested in your new, lighter frame.

Thanks for sharing this.

On a bike like this I bet it would open up places like that to a much larger group of folks! Ever heard of a KLX150? It's a street legal, but cheaper version of the trail KLX 140 in the US. (Both have 144cc engine). Heavier shock, cast swingarm and other parts it brings the weight to 250 lbs ready to ride with 9 rear wheel hp and poor suspension for a 95lb person. The good thing is they are uber reliable, cheap and everywhere now. BBR got a big bore/carb kit that can get it up to 14 rwhp and KX80/85/100 suspension bolts right on. I wonder if a guy like you could get the 250 lber down to 200 ready to ride?

About Honda CRF250L

Advertised at 144 kg, i weigthed it at 141 kg with the bathroom scale all wet.
As stock (euro model) it doesn't have the emission stuff, side reflectors and big plate support, that seems right with Ramz weighting (309 lbs), with 7.7 lt (2.06 gallons) http://rickramsey.net/CRF250Lmods.htm#weigh

To "un-weight" 10kg (22 lbs), I removed some unuseful things (still keeping it here legal), as ..
Chain guard, Helmet lock, Blinkers, Saddle strap, Right rear mirror, Passenger footpegs

.. and swapped heavy parts with lighters ..
Rear fender eliminator, UFO headlight plate, FMF exhaust line (w/ fuel controller & db killer), Alu sprocket (w/ speedo DRD), A123-4cells battery

Now it weights 131kg (289 lbs), bathroom scale controlled with 34.5 in seat height. Matter also where the weight is.
With added performance (and 1'300$ more to the bill), i'm pleased with the result for a daily driver + WE offroader
