G1 or J1, is there any real difference?

OK, so I have a tiny insignificant budget, but I want a 6R. I kinda like the J1 (I think its the twin headlight that does it) but there is (what looks like) a MINT G1 near me for sale, which is well within budget.

Is there any reason someone can give me that I will be missing out getting a G1 over a J1 (other than the headlight looking 10x better)?

Cheers in advance

A bit more power 112 bhp rather than 109, J is slightly lighter than G, rear tyre 180 (J) rather than 170 (G), added 5 grease nipples on swing arm and shock linkage in J, better generator and coils in J.

That's all I know about.. possibly more. J is just more refined. I would defo pay a bit extra to get J rather than G.. But do yourself a favour and get A1P

The J had more power but the truth is it's a small amount 98% of riders would never notice. The biggest NOTICEABLE difference between them is that the J came with much better brakes, which were notoriously weak on the G. There were subtle differences but nothing you would notice unless you were highly skilled and pushed the limits.

If your budget is really tight then not much difference on the road
as mJZ says the little differences are worth the extra and the a1p does not have a bird cage plus a 636 carb'd engine.

good luck

I have put the differences down before but wont go into details now
a J model engine has a lot of light weight redesigned parts ie crank rods pistons etc over the g model .....it is a far superior engine
redesigned electrics even down to using stick pack coils ......
so no its not a g with twin headlights .....there is a lot more to it
valve cover ....sump......clutch cover etc made of magnesium
had an internally braced swinger which a g didn't have etc etc
the list is pretty long

an a1p is a j with a large cylinder bore ....and no birdcage......that's it

The brakes are the same on the g-j just depends what pads and how you use them.. The g you can run a 180 rear tire cos I do and love it... Like anew people have said its a tad lighter and a bees dick more power but who can tell the difference right? You can do a twin head light conversion to the g to make it the same as the j if you can find the parts for cheap.. Any pics on this g you have found?

tinted screen, hel lines,intergrated tail light, rearset adjusters, K&N air filter, +4 advancer, -1 front, pazzo knock offs, ape cct, zip tie mod,07 shock + rear disk, 08 swingarm, vernhil rear line, 636 exhaust with dan moto cf can, Kleen air mod..

still lovin forever!

The G and J rear wheel is also identical so no issues at all putting the 180 tyre on.

Didn't realise A1P had no cage, lot of people get a ZZR 05-08 bracket for their J anyway so wouldn't have thought anything of it.

Its all a matter of skill, the F is a cracking bike and would keep up easily unless you're at the limit.

I ride an N reg E model (ZZR 600E) which is even earlier and I'm faster than a lot of people on much, much newer bikes.

One of my track pics has a 636C behind me I'd just burnd past on Park Straight at Cadwell

That was my first and only track day too!
