So, w ith ou tfurther ado ...Tank God for. theRE-5. Here isthe bike that, according to Su-zuki, provided a "welcome tothe Rotary Age". Itsaid cheer-io to it, too, and remains the only Japnneserotary-engincd bike ever to see the light ofday here. Itis an undeniable oddball andcertainly one of the most interesting mo-tor bikes ever made. Thank God for theRE-5.</p><p>David Jupp owns around 20 Japanesebikes of varying vintage, some of themeven rarer than the RE-5. But nothingattracts curious onlookers - bikers or oth-</p><p>erwise - with the bees-to- honey regularityof'this machine. Often, they're drawn to itby the vulgar tear-gas canister of a rearlight cluster and then held there by themultitude of other delights the bike has tooffer.</p><p>Check out the flip-top instrument pan-el. Dig the metalflake finish on the paint-work -pure 1970s,How about those quaint,round indicators. Look at the size of thatradiator. And, hey - i sn't that a ... ?Yes, itis.

During its short lifespanfollowing its introduction in 197.4 onlyaround 200 were-ever imported to the UKand Dave -Iupp reckons there are maybeonly around 25 good ones left - includinghis.

And itis smooth.'</p><p>"You can feel the road shocks and occa-sionally the transmission, but you cannotfeel the engine at ail," confirms DavidJupp. "If you rev it up and put your handon the tank, you can't feel a thing. Themetal rear number plate is a case in point:it's original and still in one piece, while ona normal bike itwould have cracked with-inweeks.The smoothness doesn't lull youinto going faster than you want" though,because you're sitting up into the wind -and then there's always the roar from theengine."</p><p>Ah, yes - the engine noise. Odd; veryodd. You imagine that if ever they were toinvent afive-cylinderthree-stroke it would,somehow, soundlike this. It's difficult toexplain, really, but it's a weird mix ofgenerator, council grass-cutter, big twinrunning on one cylinder and two-stroke (ifyou've never heard one, I can appreciatethat you're still none the wiser).

David's never caned it,but he has had it up to around a ton, atwhich point a slight weave sets in. Suzu-ki's claimed top speed for the 62bhpma-chine in 1974 was 1l0-115mph, which isabout right.
