Most powerful Suzuki RG500?
Made you look. Is this the most powerful? It’s in the ballpark, at any rate. Daytona video at end of this clip is from 2004daytonabikeweekvideo.com

I know when I heard his motor run up on a different dyno earler in the week I was very worried! His 570 makes bags of torque. Unfortunately it was misfiring and even there we could not make peak power runs. He runs more compression than me and his motor is 14% bigger than mine. Still, very good chance we will shoot out this fall at Barber, his blue/ yellow monster vs the Delta on the dyno. I think it will be pretty close but not making a prediction. GHN claimed 155 from their RG-TZ.

You know, Mark shipped one of his engines to the US to run against me at this very dyno shootout, but they had tech probems and were not able to make it for the competition. That motor of his is very strong, no doubt. My 132 here on Superflow would probably dyno in the 145 range on a dynojet inertial.

They made a bunch of 2-stroke street bikes, way back in the 70s. I think after the GT series (GT380, GT550, GT750 ) they did not have a new big-bore 2T streetbike until the RG500 in 1986. The RGV250 was a big seller in europe for many years and there were many variations of that model- it was far more technologically advanced than the RG500. In the US, though, Suzuki stopped with 2 strokes a long time ago.

At the rear wheel, the RG500 made about 75 HP, stock- I have dyno tests from several magazines. Although a set of pipes, air filters and rejetting can get an RG500 into the 90+ hp range without too much trouble.

Just curious what was the stock HP on the RG500,RZ500 and the honda ns400r

haha yea, but they’d probably end up becoming best friends and starting a club for people with record setting stock motorcycles.

I was buying parts at the shop last month, and one guy starts asking if I have a bike, and he has a Bandit 1200 in the parking lot. He then goes on to tell me his bike went 185 mph, stock, but since he “derestricted” it, it will go 204 mph. I don’t even have the energy to argue with these guys anymore… I Just told him he’s very lucky to have an abnormally fast Bandit 12. Maybe he should race the dude with the 196 mph 636!
Comment by rg500delta — February 26, 2010 @ 1:12 am
errr , ok …. your buddy should take his 636 back to Kawasaki where it will be framed in the hall of fame as the world’s fastest 636!!! LOL.. A stock 85 RZ500 is good for aound 240km/hr IF the tune is perfect (whatever that is in miles) but sure aint close to 200mph!!!(322+ km/hr!!)
Still has plenty enough mumbo to shut down a 636 though!!..
Comment by literbikedoc — February 26, 2010 @ 1:12 am
definitely take a two stroke over a four any day. i have a sh*t talking buddy with a kaw 636 who claimed to be going 195 mph one day, while still having a gear left to go through. he didnt think my ‘85 Yamaha RZ500 stood a chance. needless to say, he lost miserably. he laughed and said when i flew past him when he thought i was in the dust, he actually said “WOW” out loud in his helmet! hahaha.

Comment by heelflip964 — February 26, 2010 @ 1:12 am
Ummmm Oooops, sory, the rgv is an RGV250 rolling chassis, ta.
Comment by dwsnare — February 26, 2010 @ 1:12 am
Sheeez, pretty loud. Qwik question please. Im slotting my RG500 into a rgv chassis (keeping my old frame). Was wondering what chambers to buy that will suit the rgv framework. I was thinking of either Jollymoto or Nikons. Any wadvice would be great. Very nice machine mate, it SCREEEEMS, lol. Cheers, john (Sydney)

ameizing motorcikle, I like dat
Comment by trofii — February 26, 2010 @ 1:12 am
Thanks! It uses TZ250 cylinders, via adapter plates, TZ pistons, longer con-rods, billet heads, 38 mm carbs, TZ-ish pipes and a digital ignition with a TZ-ish advance curve. So I have tried to make it into a pair of TZ250 engines. The dyno sheet is very close to 2x TZ250 but at high rpms I don’t have the breathing, so when the TZ keeps going to its peak, mine flattens off- it makes about 90% of the HP of a TZ250, per cc.

rg500delta this bike is amazing.
Wha’t king of modification have you done to reach 130 hp ?
Comment by buzzy84IT — February 26, 2010 @ 1:12 am
What a great bike !!!!! Nice job. I wish I never sold mine. An irreplacable gem.
Comment by criticalmass181 — February 26, 2010 @ 1:12 am
There was a 240Hp V-max there one time, I don’t know how he finished up, I suppose got killed by turbo bikes or something. But it was incredibly bad-ass. There were a lot of old bikes that guys had just gone crazy with- it was pretty cool to see all the hardware that came thru during a week of dyno shootout .
Comment by rg500delta — February 26, 2010 @ 1:12 am
hmm… notice on ‘winner sheet’… 85 Suzuki GS1100E 217.7hp!!! I guess Suzuki did a lot right back in 1985, sorry, they still do.
Comment by bluebearbank247 — February 26, 2010 @ 1:12 am
LoL. blaaaaaatttttttttttttt. Hey my RS250 is a V-twin…. !
