so which is better R80GS PD or R100GS PD?
how much weight difference between the two.
WHich is better is like an oil thread crossed with a tire thread
Both weight roughly the same, R100 slightly heavier in bare form but not much, till you add a big tank and lotsa fuel, etc.
The R80 jacks, THe R100 has paralever driveshaft issues. (once in a while.) The R80 motor doesnt have the ass the R100 does, but it smoother.
R100 forks are better.
Eh. I'm kinda a paralever guy for now, because thats the one I have
best would be an R80 G/S w/ R100Forks, or which ever you find at a good price and well maintained.
G/S front end is crap, the GS rear end is crap......
The R100GS is heavier and more powerful, it is a better two-up and looooonnngg freeway-ride bike.
The G/S is lighter and smaller, a better solo machine, and better off road bike (more ground clearance) and has more "street cred". On the freeway the R80G/S easily cruises at 80mph, it's easier to pick-up when you drop it and it feels much more intuitive when the going gets less than ideal on any surface.
I've had both, and strongly prefer the R80G/S for everything... I don't have the "slipstream deflector" (fairing) on mine, so extended hours on the freeway are more tiring than my R100GS was...
I am however, biased.
Some reference material:
Also, the front end on mine works pretty darn well, but I have made a few modifications. It is almost equal to the front end of my R100GS that was also modded.
I have only ridden an 80 one time. Lobs gives some well reasoned props on the 80, can't argue with one of em.
I'd trade my 100PD for an 80 set up with a higher 5th gear if a deal came along.
The rpm at highway speed on the 80 was the only real weakness I felt the bike had. That would have to be changed for me. Sure like the idea of any GS with higher ground clearance and less weight to whip around. I have no complaints with mine though, its perfect.
They are all good though. I just got the best one I could find when I was ready to make my move. $500 cash plus my /5... I could not pass it up.
Thought you might like to see my girlfriends '71 R60/5. Birgit rode this from Mombassa in Kenya to Cape Town, and then up through South and Central America, and then through Mexico, the USA and Canada. It'd had seven owners before she found it rusting under a tree, covered in leaves and bird muck. She stripped it down to the frame with a friend and rebuilt it using second hand parts - so she could learn the bike and would be able to work on it while we were travelling. The only mods were hand guards, a bash plate, Koni shocks and home made racks and panniers. Oh and she took half the padding out of the saddle so she could hit the deck with her feet! We've no idea how many miles the bike had on it but she put just under 100,000 over the four years we spent doing the above. She took the bike everywhere I took my GS - dirt tracks, desert, mud the lot. The only hassle she had with it were with the points and that turned out to be a bent backing plate. The resulting exhaust explosions were 'interesting' as we rode through Colombia - one lot were so powerful they blew the ends off the aging exhaust pipes! :eek1
As somebody who currently owns both I have to agree with this, I know of two G/S, mine being one of them, which have fractured a fork leg below the bottom yoke when used heavily loaded for travel in Africa. The problem with the GS front end is there are no lugs for a second disc as there are on the G/S, BMW would sell you a leg with them fitted but they are no longer available, I believe it is possible to modify a right hand leg to fit the left but have not tried this yet.
The GS is a better bike for carrying a passenger and the standard seat is more comfortable for the rider. The paralever back end is crap but driveshaft life can be extended by fitting a shorter shock from the R100R, I have done this to both mine and Tiffany's bikes and they have both covered over 100,000 miles from a standard BMW shaft despite being used in some fairly adverse conditions.
In case anybody is thinking I have contradicted a previous post about not breaking down in Africa, the fractured fork leg happend to the original owner who went long way down 2 up on it.
...having fun with this one, which I picked up about a year ago.
It suffered from some PO neglect and monkey wrenching:
gummi-carbs, balky starter bendix, R100R speedometer, improperly indexed throttle cam & etc.
good compression though, now purring nicely.
needs a proper skidplate and more action.
now THAT is cool!
I should definitely be committed for this:
The GS rear end isn't crap it works well and gives a much better ride than the g/s rear. I take it you mean the rear end is crap because the drive shafts have a tendency to fail.
Great shot!!! Cool idea!!! And really good to see Jessie panniers being put to good use! A few souveniers collected there :)
I've no compaints over mine on my '91 GS. Yes my bike is on it's 4th shaft but that's over 265,000 miles, at least 150,000 of which were on rough roads with my home swinging around on the back of the bike. Balance that out against chain drive and...
However, having said that, shafts are known to last the lifetime of a g/s...
Whatever, really happy with mine. Wouldn't change the ol' girl in for anything!!!!
Had lots of bmw's but this my first R80GS , life just gets better and better
Not my first bm but my first gs
Nice place to start.
Nice! Is that an HPN modified GS?
The frame and subframe (not to mention the front end) have definitely been modified by someone. The swingarm wasn't lengethened though. Got any more pics?? Specifically one under the tank??
Swing arm looks lengthened to me, right between the final drive and the swing arm- probably one of those 50mm bolt on kits.
Cool bike, more info needed.
What front end is that and what triple clamps?
forks are of a husky , brembo brake , tripple clamps made by a enginear in New Zealand , HPN gear box ,
fame upgrade as recomended by HPN , work again by NZ enginear
parts from HPN , work done local
