[@rustomhind]

Dude the one in the video is the ypvs models. They were not sold in India. Better performance and liquid cooling than the cheaper ones sold here. I too was once a proud owner.

[@Twed]

Think the RD was suffering from a little clutch slip up the rev range.

[@TheThunderwars]

When your machine has a lot of torque and you want to preserve the clutch life, shift without clutch by just repositionning the throttle on its lowest position. On a fast twist throttle, you won't loose much time. This is basically what those so expensive "shifters" do, they cut ignition so that power is no going through the gearbox for a certain amount of time in order to enable the dog teeth to slam into another gear. You can do that with any motorcycle since they are all dogbox.

Great vid! I owned and raced three RZ350s, 83, 85 and 86 models. Ran them till I killed them, yours needs a motor from between 84 and 86, they were the weapons grade series. Congrats on being the first KZbinr I've seen who let's their RD engine rev through the powerband. I don't know if the others don't understand two stroke characteristics or are afraid of damaging their vintage engines, but they always shift too soon.

[@RacingSM]

Thank you Brian. Yes, if you watch all the onboard videos on our YT channel of our 2-Stroke bikes you'll notice we push hard all of them, from the 350, the 250's, the 500's, we have to enjoy them ! :)

[@TorquilBletchleySmythe]

@@RacingSM what are your thoughts on joining two Yamaha IT250 engines, gutting one gearbox and running them on a common shaft? You could shove it in a little CBR Babyblade frame with RD 250 expansion chambers. I'd be thinking 78' ignition timing for a dynamic crank.

[@motosmar9209]

I know very well both mascines. The RD surprises me in the acceleration.. . Thanks for the video. I love an Aprilia more, but also the older RD project surprised me it revs like an monster.

[@RacingSM]

Yes, overall the Aprilia is a much better bike, it corners very well unlike the older 350 and the Aprilia is beautiful, the 350 is just pretty 😁

[@rexnz1234]

Awesome video thanks, that sound is to die for. I owned the RZ350F (full fairing) back in the day and have a 95 RS now. Even with its handling ( call it great feedback ) I think the RZ is a better proposition for the road. The RS is way too cramped but ideal for the track. Maybe its just my age.

[@Idiotstryingtobeprofessionals]

Rd all day long

[@theblytonian3906]

From what I witnessed and heard, and as a two stroke owner and rider for over 40 years and having ridden both of those bikes, I suspect the RD/RX rider was more aggressive and experienced. The RD/RZ (country prefix dependent) is the easier of the two to to ride, which is a plus. The Aprilia RS250 like it's lower compression engine stablemate the RGV250, is more challenging to ride fast than larger capacity two strokes. The RD/RZ will also change line faster (faster rate steering). If I had to choose between the two to ride for fun on the road, I'd choose the RD/RZ (bias ply, steel frame, less brakes) although it doesn't look as cool. On the track, Aprilia RS250 (radial rims, uber rigid alloy frame, much better brakes etc). I currently own an RG500G and RGV250T BTW.

[@ericgeorge5483]

The RD every single time for me.

[@jamesrindley6215]

Always wanted a RD as a teenager, never got one, which is probably good because I would have crashed horribly. Eventually got one in my 30s and even then I still crashed, not horribly but enough to make me realize that the bike is an addictive drug, a blast, but ultimately no good comes of it. I'm a nice safe 4 stroke rider now.

[@OrangeSunshine15]

Amazing, what a way to start the day. Thanks

[@alexandersimpson3638]

I've old enough to have seen 4 stroke then 2-strokes then the advancement of 4 strokes. Most think the 2-strokes were the older engine, no 2-strokes came after 4 strokes. In my opinion a modern injected 2 stroke is not only cleaner but considerably more powerful than a 4 stroke equivalent. As for reliability, I'd say as long as you're not over tuning a 2 stroke it is just as reliable as any 4 stroke Okay, you will need a rebuild, but this said it is likely to cost the same as a major service on a 4 stroke or there about's.

[@andret4144]

Felizmente tenho uma rd lc ta quase pronta

[@jordi6795]

Correct me if I'm wrong, but a afaik, in a comparison of stock bikes between the Aprilia RS250 and the Yamaha RD350, the Aprilia is a bit faster in all aspects, also more agile/effective, mainly because of the modern design, also this is kept with minor tuning (pipes, carburation and few), but with proper tuning the Yamaha, while keeping the displacement, could match the Aprilia and then even surpassing it, then some upgrade would require the rest of the bike to handle such increase of performance accordingly.

[@franciscodieguez5187]

@@RacingSM There is no comparation if one is fully modded and one standard. Just saying

[@RacingSM]

@@franciscodieguez5187 compare both bike engine specs on this video description. Both have similar engine mods, the Aprilia has a lot of light stuff installed ( carbon fender, aluminum rear sets, levers etc) so I think the acceleration test is fair. The 350 was a little superior in acceleration due to +100cc for similar mods and similar total weight on both bikes. That's why I've said if the 350 was completely stock, it would be inferior to our Aprilia with mods or even completely stock. 👍

[@jamesw2546]

The rd has that better initial pull but the difference soon closes in the rate they accelerate. Rd wins acceleration and wins the race to the corner rs goes past n leave Rd behind for rest of lap lol

[@chrishart8548]

@@jamesw2546 it's true the old bikes will loose in the corners. The first gsxr1100 had a 130 rear tyre that's the same size as a aprilia sx50 motard think the rd350 has a 110. The rs250 will have at least a 150 section. Older bikes are crazy the brakes are small the tyres are narrow some had 39mm-40mm normal way up forks

[@gmac9841]

Not what I thought would happen, raced old 83 rz 350 against rgv 96 model, same motor as rs , every time down the straight he would pull away, . around the same top speed of 210km's but rgv got there quicker. 1 km long straight . Great bike for its age so much fun, way better than the 250. Race track was hidden valley Darwin. NT

[@RacingSM]

Yes. If both are 100% stock the RGV / RS 250 would be superior in acceleration / top speed ( on track / corners the difference would be huge in favour of the 250 )

It looked to me like the RS started this "test" below the powerband in every single test. You could see the RD's rpm and the RS's rpm. The RS doesn't even start pulling till 9000rpm and the redline light was set very low. It also looks like (and sounds like) the RD has a fair bit of work done to it?

[@RacingSM]

Only for 1 time the RS was bellow 9000rpm, on all the other situations the RS was on the powerband zone The redline is set for 12 500rpm @ RS 250, not low :) Our RD 350 ( the Aprilia RS is also ours ), like the engine specs on the video description says, the cylinders are OEM ( no porting, nothing at all ), only the OEM cylinder heads were modified ( more CR, different squish and uses O'rings ), it has HPI Ignition, TDR 250 28mm carburetors, modified OEM Airbox ( no sponge inside ), Boost Bottle, JL exhausts and 15 - 39 instead of 17 - 39 That's not much work at all .. comparing for example with the TDR 385 project we are building at the moment ( based on RD 350 engine ), that one has a lot work .. ( OEM cylinders bored to 65mm, very agressive portmap with huge areas, 34mm carburetors, custom boost bottle, will have custom made exhausts etc ) .. that one is what you can call a " lot of worked engine " :) If this RD 350 had more work we would say what was done, no problem telling at all, but it only has what I've mentioned before :) But I agree, the sound of the 350 is really incredible, we are also surprised by the overall good result and sound based on the small mods used.

[@fastr1red]

@@RacingSM Ah ok. Yes understood. Very well done I knew the RD was modified. You've done a fantastic job on it.

[@RacingSM]

@@fastr1red Yes, it has some mods, but the engine "internally" / cylinders is stock :) Both bikes are ours, but we know that the Aprilia overall is galaxies away better than the this RD 350 since it has OEM wheels and suspensions ( only RD 500 brakes and stiffier suspensions springs ) But we prefer the 180º ignition sound of the 350, each one has their good and bad stuff :)
