"Rat" bikes.

Jetho: has the true idea of a rat bike so unkept that a rat won't go need it.
 
When I think of a bobber, I think of a bobcat - short stubby tail. I think that's where the term came from originally.
So the fender gets yanked, the seat shortened, etc ... you get the picture.
 
it's easy to be dismissive of rat bikes, but some of the bikes on that ratbike site are unbelievable feats of engineering, and the owners deserve recognition for their skills.
http://ratbike.org/docs/2006winner.php for example, is a Suzuki RF900 (I used to have one , lovely bike)


Course, most of them are piles of rubbish that should have been incinerated long ago :-D
 
Well I HAD a nice ratbike:

Unfortunately I messed it up:

here is my rat bike !!! all the work that was done was for function only. turns out that it also looks pretty sweet too !!! no gauges at all. nothing extra, only what is needed !!! this bike was built to handle and preform. so much better than the stock version!!! it has gsxr parts, honda parts, gsx parts, bandit parts.

See thats more of a street fighter to me...its too pretty to be a rat bike...Nice work BTW looks great...betcha it runs like a scalded dog!

Gotta agree, that's definitely more Streetfighter, Duke. I've seen it before, and I still love it! Trying for something along those lines myself, only mono-shock (Busa) rear end.
 
definately symantics here...alot of what ive seen i would more consider a cafe or a streetfighter..."rat" bikes by classic definition are what was said earlier...its just a crusty old beater that still runs and runs good...the owner is more concerned with riding than polishing....bobber, chopper, cafe streetfighter whatever...they usually dont involve alot of mods..when it rusts..it gets painted with rattle can..more often than not..flat black..

my bike started out as what one could consider a rat bike i guess...but when its done it will be a cafe bike...fine lines..and some people get pi$$ed when you call thier bike something that they think its not.

by my definition:

Bobber: rear has been cut much like a chop, but little rake to the front, usually a rigid or semi rigid suspension

Chopper...see above, but add lots of rake..

Cafe...Vintage UJM (usually based on standard models, not LTDs or Ls in this forum, or Customs in a Honda forum) OR a REAL cafe roots bike being something from Europe, usually a Triumph or Norton or BSA, stripped down and modded for speed and handling...no perks no frills

Streetfighter...see above except based on a modern sportbike using modern tech and parts


Thats basically how i break it down...just my view...

I whole-heartedly agree with your descriptions here, but again, just someone's 2-cents worth.
 
Here is a good example of a ratbike:
Ratbike1.jpg

Not to nitpick, but I believe something like that would be considered an 'adventure bike/cycle'. The way it was explained to me is Rats are dirty, dull, and aged from years of not caring about looks, with some ghetto-engineering thrown in for quick fixes. Adventures are intentionally distressed and loaded down with stuff to make them look crazy......
 
If ya wanna see some rat bikes go to some big Harley rallies. (No I'm not brand bashing) The Harley crowds often have rat competitions. These bikes are generally put together with parts from many different models/manufacturers. Usually they are low budget beaters, though I have seen countless rats at rallies that were as done-up as the one in the photo.

Bobbers came about at the end of WWII as the returning GIs removed the front fender and any other heavy/easily damaged parts they could to lighten their bikes for such sport as flat track racing. At this time bobbers were mostly Indians and Harley's as the japs did not have any full size bikes in the US at that time.

Choppers originated on the west coast shortly after the bobber thing got started. These bikes are defined that the frame has been chopped. Some got the raked out front end, some became hardtails, I have even seen some choppers that were frame-raked in the center giving the broke back classic hot rod look.

Cafe racers originated in Europe in the 40's and were mostly smaller than 500cc. Lightweight and nimble But rarely good for anything over 100mph on the street. Mostly all euro bikes as again the japs did not make full size bikes back then.

Street fighters also originated in Europe, but within the past few decades. These bikes came about because the job of motor-courier is huge over there as their cities are much smaller and denser than ours. These bikes quickly had their plastics crashed off or removed, moto bars improved slow speed agility. These are usually japanese sport bikes due to their economy, performance and agility.

I have tried to write this as unbiased as possible, and there are many possible interpretations and grey areas. I have seen far to many people squabbling over whether a bike is a chopper,bobber,cafe, etc. The differences are huge and many bikes fall into multiple categories.
 
Alright, as a new ratbike owner, I've gotta get in on this:
ratbike.jpg


Planned paint scheme was flat black with a flat white stripe. After the almost-dry black coat got rained on, I said forget it and put it back together as is. Now that's the ratbike spirit! Hasn't even been washed since I bought it! Also note crappy seat repair with Shoe Goo and old Suzuki hand grips.

Waitaminute.... Wrong rat?:-D
 
treading into cafe with it hehe but it looks sweet.!

If that's at me, then yep!

Basically, I imagined a bike like this a looong time ago (rat/bobber/cafe/thing). Got this bike most of the way through before finding out what a cafe racer was....was kinda neat. When 'improving" the bike , like making a new seat, I've been working in a lot of cafe inspiration....to the point where I am probably going to pick up a '78 GS 750 this week to turn into a proper cafe so I'm not tempted to change the 450L into one :shock: \\:D/
 
Is this a ratbike then as its matt black
spondonz1000.jpg

That's definiteley not a rat bike. It's more of a track day special with that custom frame and all the other tid bits. True, rat bikes are flat black for the mosty part, but what mkes it a rat is it's low cost and "beat up" appearance. A rat bike usually looks like someone took a bunch of parts from a junkyard, slapped them together and put two wheels on it and called it a rat bike.

This is a pretty good example of a rat bike, low budget (usually less than $1000 in total) and junkyard dog appearance.
