In a world focused on horsepower, innovation, and speed, old bikes can get overlooked. The cutting edge never remains stationary, and today’s world-beater is tomorrow’s target. But while some riders focus entirely on the here and now, there are those who have a penchant for the bygone. And, among those, there’s one bike they’re choosing more and more often. It's not a new bike, nor is it even a modern classic motorcycle. It's over 50 years old. And it's as good today as it was when it first hit the streets. Vintage Bikes Can Look Modern, Even Today MecumJust because a bike is old, doesn’t mean that it can’t look new. The basic motorcycle design of two wheels, a tank, some handlebars, and a seat only has so many options and, when you consider the 1990s were a golden age of motorcycle design, you’re going to see the same patterns continuing.Take the Honda NR750, for example. The bike was light years ahead of the competition at the time and, realistically, it still is today. Its full fairing, carbon fiber bodywork, and single-sided swing arm are all elements you could expect today, let alone back in 1992.Honda struck again with the CB400SF. Produced in the same year, the naked bike’s timeless design has remained largely similar throughout its 34-year production run.DriveTribe/YouTubeAnd who could forget the Ducati 916? The bike took the world by storm on release in 1994 and is still one of the most beautiful bikes ever created. The race-inspired aesthetic, under-seat exhaust, performance, and sophistication made it “the very essence of Ducati DNA”, according to Ducati themselves.Particularly at a time when everything is increasingly digital, people are harking back to when things were more analog. And vintage, retro bikes have that in armfuls. Why Vintage Bikes Are Gaining Attention Cycle NewsVintage bike sales have always largely been driven by nostalgia. People want the bikes they grew up with but couldn’t afford at the time so, when they grow up and get a bit of money, they buy them. It’s like fashion, with a 20 to 30 year lag between initial popularity, the thing becoming old, then a revival. We’re seeing it now with a rise in the price of 1990s bikes like the Honda VFR750R RC30, Cagiva V593, and the Honda RC45.The other side of that is the decline in interest in older bikes, as the market ages out and there’s nobody with the sentimentality to buy them. And while that’s always going to be a part of life, it’s not always the case for everything. Take, for example, the Yamaha RD350. The Yamaha RD350 Is A 50-Year-Old Rising Star Bring a TrailerYamaha was experiencing a purple patch in the early 1970s. They were winning on track in the lower series, dominating the 250 cc class, winning races in the 350s, and had wins on the road with the FS1-E moped and R5 350 bike. With so much success, Yamaha wanted something that could dominate the mid-size market, not just competing with other 350s, but taking the fight to much bigger bikes, too. With that aim in mind, it set about making the best of all worlds. What came was the 1973 Yamaha RD350.Essentially a road-legal race bike, the RD350 mixed performance with lightness. The two-stroke engine was chosen in part as it had fewer moving parts compared to the four-stroke versions, meaning the heaviest part of the bike could be lighter. It also used reed valves, which are primarily used in two-stroke engines to control the air-fuel mixture entering the crankcase. In short, they provide torque induction which increases the power without adding weight.Then there was the chassis, which took inspiration from the TZ series racing bikes. These were the same ones that had taken riders to the top of the 250 cc championship in 1972 and, while the road-going RD350’s chassis was heavier, it was still designed with lightness in mind. Other areas were highlighted for lightness, like the relatively small fuel tank (only 4.1 gallons) and simple bodywork, in Yamaha’s war against weight.Bring a TrailerIt all made for a bike with a compelling power-to-weight ratio, the entire thing coming in at just 342 pounds wet. This helped it to challenge bikes with far higher displacement, earning it a “giant killer” reputation, particularly on twisty roads. Agility and nimbleness were far more useful than outright power around tight corners, which helped the RD350 to keep up with bikes like the much more powerful Honda CB750 or Suzuki GT750. It would be beaten on top speed by the bigger bikes, but its top speed of 105 mph also made it the first 350 to break the 100 mph barrier, adding yet another positive to the bike’s already exciting spec sheet.Unsurprisingly, the bike reviewed incredibly well. It sold incredibly well too, especially given its $839 price tag in 1973, though this did increase to $1,071 by 1975. 1975 would also be the last year that Yamaha would make the immensely popular RD350, putting the bike to pasture after a relatively short run in favor of the incoming RD400. Why The RD350 Is Having A Resurgence Bring a TrailerBikes that are “firsts” never really go out of style. They might wax and wane in terms of popularity, but being the first to achieve something gives a bike that extra bit of excitement that just can’t be manufactured.Being the first 350 cc bike to clear 100 mph is certainly one part of its legacy, as is the race bike for the road attitude. But it’s that giant-killing name it made for itself that helped it to gain its cult following. That’s what’s helped the bike to break out of the nostalgia trap and find new audiences, new riders, and continued life.Such is the popularity of the RD350 that, even over 50 years after the bike’s demise, whispers suggest that it could be on its way back, partly led by Yamaha filing trademarks for RZ350. The rumors do seem entirely fabricated, propagated by AI-voiced channels hoping to fool unsuspecting fans, but this is all this for a bike that only had a three-year production run over half a century ago. Whether the bike is truly on its way back or not, the RD350 is still considered among the best two-stroke motorcycles ever built, even despite it being on the older side of 50. The RD350’s Collector Future Bring a TrailerThe RD350 is already a popular collector’s item, commanding prices around $5,000 on average. Restored or restomodded bikes can go for more, especially as the number of models in good condition is only going to decrease. That helped a 1975 model with just a single mile to sell for $12,050 in 2024, and another ‘75 edition with just 4,000 miles to achieve five figures in 2025.It’s a fitting legacy for a bike that showed you don’t have to be the biggest, or the fastest, or the quickest, to still be memorable. Nor do you have to rely on your market to age into a position where they can buy them. If a bike is good, it’ll find its market. If a bike is great, it’ll grow that market. The RD350 is still growing its audience, even 50 years after it was stopped. And that’s the mark of something truly special.
