Yamaha has pulled the cover off a Ténéré 400 concept; needless to say, it has my attention. I’m doubtful Yamaha built this machine as a reply to my open letter, but I’m optimistic that we might finally be looking at something close to the motorcycle I asked for.

In late 2023, I published an open letter asking Yamaha to revive the 350. Among my proposed “trifecta of tree-fiddies” was a Ténéré 350: an enlarged twin cylinder from the R3 stuffed into a bespoke adventure frame, bringing 37 HP, at least 3.5 gallons of fuel, 10 inches of suspension travel, with a 21/18-inch wheel set, and ideally, tipping the scales close to 350 pounds. This new concept could be that motorcycle, albeit with a different engine configuration. However, there are still significant blanks on the spec sheet.

Folks at ADV Pulse identified an apparent single-cylinder engine, 21/18-inch wheels, and KYB suspension in their reveal coverage, but Yamaha is still holding official technical specifications. Their estimated 7.5–8 inches of suspension travel was a visual assessment, not a confirmed figure. Displacement, horsepower, weight, fuel capacity, and price remain questions. There’s plenty to discuss without pretending those questions have already been answered.

I’ll concede, I’m marginally disappointed by the apparent absence of a twin. There’s still an argument for smaller parallel twins that offer the adventure-bike experience without the price of admission associated with larger machines. Smoothness and willingness to spin make a difference on pavement, particularly when the trailhead is several counties away.

That said, a single may be the right decision. It presents an opportunity to control cost and, more importantly, weight. Whether Yamaha actually capitalizes on that opportunity is what interests me. Despite the “400” label, I have a suspicion Yamaha plans to take the mill from the new RW350 and use it to power this new T4 concept. Yamaha claims the 327cc RW350 mill makes 29HP with 23 foot-pounds of torque. I would hope to see a modest bump in displacement to call this a Tenere 400, but if not at least a modest bump in performance. I can’t fault Yamaha for wanting to use powerplants across multiple models. I’ll hold final judgement until we see the official engine stats.

My demand for 350-pound curb weight still stands, however. I recognize that getting a small twin to that figure might be ambitious; a single makes the proposition more plausible. I want something lighter than the KTM 390 Adventure R and as close to the CRF300L Rally as Yamaha can reasonably manage. I grow tired of manufacturers applying the word “adventure” to motorcycles and using it as an excuse from doing the difficult work of removing weight. The Honda also shouldn’t remain the default answer for riders seeking a lightweight adventure thumper. Between KTM, Rieju, Voge, and Beta, there’s growing interest in this space. Yamaha has an opportunity to put a serious contender among them.

Suspension is equally important. I would be disappointed if a smaller Ténéré arrived with travel comparable to its larger sister. I understand the business argument for sharing components and re-valving them for a lighter motorcycle, but I’m still asking for at least 10 inches and proper adjustability. The 390 Adventure R already offers approximately 9.1 inches of adjustable suspension travel and 21/18-inch wheels. Yamaha has a competitive benchmark to consider. Considering the T7’s popularity over the 890 locally, I’d like to see a shot across KTM’s bow to maintain that market edge.

My perspective has evolved since that original letter in 2023. Back then, I was still racing my Triumph Scrambler. Shortly afterward, I bought a Ténéré 700 and spent considerably more time touring and becoming comfortable wrestling a taller, heavier motorcycle through difficult terrain. I’ve also accumulated more long days on my WR250R and spent time aboard the Ibex 450 and Himalayan 450. With roughly 2,000 miles on the Himalayan, including plenty of highway, I’m more willing to concede that a properly executed single can be perfectly agreeable over long distances. I still prefer twins, but I’m less dogmatic about the cylinder count.

What matters is the riding day. I want to leave the house, spend a couple hours connecting interesting roads, disappear into the woods, and ride home. Short interstate stints should be comfortable enough, with some passing power remaining when a headwind arrives. I understand a small single won’t deliver T7 performance, but I’d prefer to avoid holding the throttle against the stop simply to maintain traffic speed.

It also needs sufficient fuel. My original request was at least 3.5 gallons; today, I’d call 125–130 miles between fuel stops an absolute minimum. My old CRF250L’s roughly 90-mile range was a considerable inconvenience that I have no interest in revisiting.

The more I consider this concept, the more I wonder whether it could replace my WR250R. I’ve been waxing poetic about a hypothetical KTM 690 Rally occupying that spot in the garage: something that would let me ride farther to the good stuff and tackle terrain I’m less inclined to attempt on the T7. A small Ténéré might serve the same purpose, provided the compromises make sense.

My WR weighs roughly 300 pounds and will run down the highway, but I don’t particularly love having to keep its engine on the boil. I’ve often said I’d prefer the CRF300L’s engine character in the Yamaha’s chassis. A Ténéré 400 that threads that needle, adds wind protection and better highway manners, and preserves most of the WR’s off-road capability would merit serious consideration.

Finally, I think Yamaha needs to keep the price around $6,999. Restrain the electronic wizardry and put the money into suspension, manageable weight, and a useful engine.

Ultimately, I want the road comfort I expect from a Japanese adventure motorcycle and the off-road prowess people imagine when they hear “Ténéré.” If Yamaha can deliver that combination at the right weight and price, my WR250R’s place in the garage might become less secure.

Am I asking too much, or is this exactly the kind of motorcycle Yamaha should deliver?
