The new UJM

Discussion in 'Bike Reviews, Questions and Suggestions' started by ibast, Aug 28, 2006.

  1. Back in the 80's motorcycle journalists used to complain that there were too many 4 cyclinders in the market and not much else.

    This morning I did a cquick calc and come up with 32, 4 cylinder engines on the Australian market. 3 of those being v-4s

    And the number of twins? 46!

    Sadely there are only 4 triple engines available. perhaps this should be the next journalistic push.

  2. And with the rave reviews the Daytona 675 has been getting I wonder if the Big Four will do something similar...
  3. I doubt it. Inline fours rock!

  4. And this relates to UJM's how?
    A UJM can be single,twin, four and I think you'd even call a CBX1000 or Z1300 a UJM.

    But yeah, I get your point. It's surprising there'd be so many more twins then fours, considering fours dominate not only the press, but also sales
  5. Actually, wouldn't that be transverse v-twins?

    Seriously though, I like my 4, but 4-s have their pluses and minuses.
  6. :?:

    Singles and twins I don't think so.

    I am fairly sure the description UJM (Universal Japanese Motorcycle) used to refer to the abundance of in-line 4 cyclinder 4 stroke motorbike that Honda, Kawasaki, Suzuki and Yamaha used to punch out in the billions way back in the 70's.

    Some of our older (Cough) I mean, more experienced gents may be able to confirm this for me?

    As for myself, I am a proud owner of a vintage UJM, a Mighty Red Hinda CB400/4. It's a bueatiful little number and I can see why the SOHC CB range developed such a devoted following.

    I am sure the GS range from Suzuki, as well as the Z bikes from Kawasaki have similar passionate followers of the UJM.
  7. The "universal" bit refered to the use of in-line 4s in all sorts of bikes.
  8. What, add an extra 75cc to try and whip everyone else? :p :LOL:
  9. :shock: 46 twins :shock:

    Does that mean 92 singles :LOL:

    Actually that's an interesting set of stats; I guess it means that the UJM is still a Jap 4, but there's lots of other choices......
  10. I believe the term UJM referred to the way teh Japanese were making motorcycles in the 70s'. It was almost a derogatory term, some thought the bikes were soulless.
    Typically, it's a Japanese inline four motorbike, with forgiving handling, lots of safety features (new for that time, like clutch switches, gear switches to prevent starting in gear etc). The Japanese bikes from the era mostly looked very similar as well and shared many similar features, even compared to different models. One manufacturer was even using a Kawasaki four under licence in one of their bikes to fill a gap in their model range....
    Of course, with teh lack of soul, came unheard of reliability and trouble free riding, something some markets (US) couldn't quite comprehend......

    Regards, Andrew.
  11. Actually if you just look at the japanese then it's 29 to 27 in favour of the twins.

    I have included the Yamaha 16,17 & 1900 cc cruisers as 3 seperate engines, which if I knew more, would probably not be the case.

    If you count them as 1 engine then it's 27:27.
  12. I've always taken the UJM to be a naked inline four, the original being the CB750.

    The sort of bikes coming out of Japan in the 70's and early 80's, before you got the sort of specialised market niches you see today.

    A current UJM would probably be something like a Hornet.
  13. The phrase did fade once they started making full fairing bikes in the mid-late 80's so in a sence thats true.

    In my mind it was a reference to the standard use of an in-line 4 for Japanese bikes and untill I did the nubmers this morning I thought it still true.
  14. The UJM still sort of exists I reckon, the 600 or 1000cc supersports class seems to be basically the same bike with a choice of four different badges. The original UJMs were all about making the fastest bike possible (biggest engine that'd fit the frame), something they're still doing. They may no longer be producing bikes with engines too powerful for the frame but are perhaps making bikes that are simply too fast for public roads. Probably why sales of cruisers and scooters are increasing so rapidly.
