    I saw that too. They say it's a replacement for Ninja 300, and judging by modest power gain at lower RPMs and jump in torque they probably just stroke existing 300 from 49 to 66mm, co-incidentally what CB500 use.

    Will give them upper hand over 313cc G310, 321cc R3 and 373cc 390 Duke, CB300 and on equal footing with CB400 in Japan.

    From what I've researched, the 286cc from Honda is the new minimum for all tarmac conditions for the average sized human on the planet.

    Have a DR650, and I think BMW nailed it with the 313cc, cause they both have 34hp, which allows 80mph crusing on the Interstate all day long.

    The Chinese Loncin DS8 will use the 652cc Rotax engine in their 436lbs Adv Touring bike.
    I've never ridden that engine, but think she would be at the end of the spectrum for the Thumpers.


    286-652cc

    Not sure.

    I demo road the R3 and thought 321cc p twin was well balanced for a All-Rounder.
    Less than 400lbs and all day Interstate slabbing. That is all most of us need.

    It depends 35hp may not be enough in the Planes with 35-50mph side wind and side cases; in conditions like that my 650cc Wee2 maxed out at 85mph. Plus you loose ~10% due to altitude and bad gas.

    Another problem those parts of the country have higher speed limit, 75/80/85 so passing on loaded bike could be eventful.

    The interesting part of displacement bump is low end torque which has gone from 18 to 27lbs

    All touring on a MC is a compromise.

    If you want to be less than 400lbs wet, you have to pay the Piper somewhere else.

    When I toured out west, I got lucky heading west, cause it was not too windy in May. When I came back in Early July, the wind was at my back.

    The worst wind was in February in Texas. Really bad cross wind!

    But I wanted a high speed low drag KLR to ride on dirt roads all by myself and and stealth camp.

    A good thing about buying a small displacement bike is you can take your time on your trip, cause you have lots of money left over to just stay at motel a couple days or take a slow going back road. Time is money, and you should have plenty if you buy a $6,000 bike vs a $9,000.

    I wonder if it does make it to production if it will have the new trellis frame or will it be the 300 frame. I think with the trellis frame its sales will be fantastic, possibly stealing prospective buyers of the KTM rc390.

    I would love to see it too but most likely it will be a patched 300, as 300 was patched 250, as 250 was patched GPz.

    Versys X frame is very much the same design they had to reshuffle jigs for subframe but otherwise..

    Point it is a low budget bike, don't expect miracles

    Sadly, your probably right. But, I'm hoping the 400 will be a bit to big for the 300 frame and will fit very comfortably in the 650 trellis. If such a thing happens, there could definitely be a little brother in my stable, hell I'd even consider not upgrading the klx to get one.

    Old 400 was de-stroked 650 and it was too heavy, same weight as 650.

    To increase 300 to 400cc they only need 16-17mm more stroke, 1/3" wider crank.. the engine doesn't have to change that much. New crankshaft assembly, balancer, cams.

    Would that extra 100cc pose a stress issue on the 300'S frame?

    Well if quoted numbers correct HP only grew 20% to 43. EX500 had 51 and used similar frame design.

    They probably had to put bigger throttle bodies but we can only speculate at this point, 3 more weeks!

    The 300 engine in the Versys-X is Euro 4 compliant. It will be available as a 2018 model in Europe.
    This doesn’t mean we don’t get Versys-X 400 later.

    Kawasaki has worked wonders to gain so little with another 100cc! The Ninja didnt need a new engine, a higher state of tune with more top end, higher redline maybe but the biggest fail is the frame, suspension, brakes. I could flex mine on most good street turns in the mountains.

    They really do just suck. The 300 engine deserved npbetter than that barely tweaked 1980s frame. The R3 is stout and not that much different but you can see the way the steering tube is attached, the swingarm pivot area. They did the math.

    Im off the streets for now but they all better hope Benilli doesnt figure out their engine tune and weight reduction cause that thing has the potential to embarass all the current class 300 bikes.

    If this is stroked 300 engine it would make more sense in Versys X than Ninja

    As soon as somebody broke rank out of the 250's, this was inevitable. Ninja 300 -> CBR300 -> R3 -> GSXR300 -> Ninja 400 -> CBR400 -> R4 -> GSXR400 -> Ninja 500 -> CBR500 -> R5 -> GSXR500 -> ...

    Well Japanese mostly driven by local market and in Japan the cut off is by CC, 250, 400 and up. Over 250 is more tax but over 400 you need big bike license. CB500 is sold as 400 in JDM and 300 didn't make any sense.

    As long as the bikes don't go over 400lbs, I'm cool with more displacement.
    The new DL650 is 471lbs with 5.3 gallons.

    I think the 471cc from Honda is up to 427lbs. 4.6 gallons, and is in a hard spot.
    About 35lbs lighter, but down 20+ HP.
    Granted, the bike most likely feels way lighter.

    If the Versys 650 gets updated for 2018, the Honda 471cc platform will be in more trouble. It could be just 20-25lbs lighter.
