rd350 ypvs wet weight
just took the 350 for mot and was shocked at the weight. its a f2, totally standard barring a set of race pipes. with maybe 2 litres of fuel in the tank she was 141kg ready to ride. i always thought it would be more as the frames and wheels weigh a ton!
Re: rd350 ypvs wet weight
to make a comparison last week i took a tzr125r belgarda for mot and it weighed 127 kgs. i just assumed the rd would be alot more

Re: rd350 ypvs wet weight
Thats about right US bikes full with catalytic converters are stated at 370 lbs that puts it around 160 kgs.
With lightweight pipes & some other parts you can drop 40 pounds on these lil bikes. Many might be surprised if they weighed various pieces versus newer stuff in some cases its actually lighter or very close. I know my front end conversion weighs MUCH MORE more than the tiny thin stock forks and wheel. That's why these things were/are such a blast to ride you can easily strip more weight off them & just as easily get another 20 h.p. as well:-)

Re: rd350 ypvs wet weight
I plan on getting my street bike down to about 260 lbs (118.2 kgs). It's an FII...and I'd like to see about 55 hp at the rear wheel. I'm much larger than I used to be. Not fat though.

Re: rd350 ypvs wet weight
250 pounds might be a very hard sell, That is over 100lbs lighter than a stock bike. Would be great but I don't think you can get a stock framed RZ down below the 280 pound mark probably 130 kilograms I'm guessing.
To get there I think you would have to have high use of carbon fiber and titanium even then it's going to be hard.
but any weight off the machine really makes up for it in performance these things really come alive and into their own with a weight reduction program I am an easy 40 pounds heavier then when I had my first ones the performance will be substantially less without motor work. I remember back in the day a 200 pound rider stood no chance on an RZ, now I'm there...lol

Re: rd350 ypvs wet weight
I had my LC down to about 260, back when I was 145 lbs. Chambers were about 3 lbs each, no sub frame, signals, air box, signal wiring, battery, cancelling unit, nothing extra, except a full fairing. I was going to eliminate the kick start and cluster, the oil pump and oil tank. Would have been quit a bit lighter. TZzs are in the 200 lb mark, 210ish.
I'll let you know what mine weighs when I get there.
I'm a fatty at 215, but I'll find a way to make it go as fast as a 145 lb'er.

Re: rd350 ypvs wet weight
I never weighed mine, but once I got rid of the full fairing and stock pipes and a few other useless bits the weight was significantly less. With a bike that small you don't need to shed much weight to notice the increase in power. Stock F2 pipes are over 20 lbs. JM or Lomas with be 1/4 that. The full front fairing and fairing stay are quite heavy. The rad shroud can go too. Get rid of the heavy stock mirrors. It's easy to lose 10 lbs or more up front. Drop 20-25 lbs from the bike and you'll be very surprised with the throttle response. Dropping weight is easier and cheaper than adding HP. Well, to a point I suppose. If you want to be picky and use Ti hardware and parts it will get very expensive.

Re: rd350 ypvs wet weight
Thats a nice hybrid a fantastic handling bike and could the best looking sportbike ever, now with a decent amount of power too not the jewel of a motor like the 400..but brute force.snad380 wrote:. im hoping for under 115kg with my rvf version

lol, I was about 10 pounds over you now I'm about 10 pounds under you. Your build sounds similar to mine track oriented streetable YZR as light as possible mostly will do Starbucks runs and track days, no racing due to severe arm pump and awful carpal issues. Just a fun way to relive my youth with my trusty lifelong friend the RZ

Re: rd350 ypvs wet weight
My race RZ has 132 kg "ready to race".
It's using a R6 frontend, RGV250 rear. Ready subframe is aluminum and also the fuel tank.

Re: rd350 ypvs wet weight
Thanks questo. That was a early pic its now a lot further on.
132 ready to go for a rd is nice and light. I had a nsr250 mc18 years ago and in track trim was under 115kg ready to ride. Nothing fancy. Just fibreglass fairing and race pipes. I did find it ended up being pretty unstable on the road! Steering damper please!

Re: rd350 ypvs wet weight
That's right along the lines of what I was thinking a stripped race bike with an aluminum tank subframe front and rear swap weighs in at 291 pounds so to get down much lower is going to be very expensive. All things considered for what it is with this size of the frame it's a fairly light weight bike even by today's standardsMK wrote:My race RZ has 132 kg "ready to race".

Re: rd350 ypvs wet weight
Just bought myself one of these. Comes spool gun ready (for aluminum welding). Just need the spool gun, a small gas cylinder and 220v in the garage. Gonna try my hand at replacing the subframe with an aluminum one. Will give me a reason to practice at it and shed some bike weight at the same time.
