I am hoping one of you gurus can sort this for me. I have bought an SR500 and it all seems pretty stock. It has been previously registered as 1982 bike but I am wondering if this is corrrect.
This is what I know:
Compliance plate reads 4/78
Engine No 2J2 1507 785
Chassis No 2J2 507 99
It has disc brakes both front and rear
Waddayareckon?

Hi mate, I would say that you have an E model SR500. 1978, first model. Both the E and F model has a disc front and rear...but no other models have this as standard. Look here on our site for some pics... www.warouw.com/sr500act/Mine have matching serial numbers so the engine may have been changed out at some time. The '81 model has an engine and frame prefix of 4F3... SR  |

I think that you probably have a bike that is made from 2 looking at your serial nos ( they are the same if the bike is original) . Stu I think the last of the 82s they bought into OZ they dug out a few 78 frames as I've got a 82 with a rear disk( the frame & swingarm are different on the drum rear models) . I would never have worked it out but I had 2 82 frames that were different , there is also a bracket under the seat that they omitted from the construction cheers Dave.

Thanks Guys,
so the mystery is not 100% solved (not that it really mtters I guess). I may try to register it as a '78 therefore not needig to comply with the stricter noise regs for the post '80 bikes.
The issue I am havnig at the moment is that my local Yamaha dealer is telling me that I definitely do not have a disc on the rear (not sure why he thinks I would lie about something like that), so do you guys have a part number (or a good contact for parts) for a caliper kit?
cheers
Stew

Really, not seen that before. Send some pics of the bike, I'd like to have a look. No info I've ever seen (until your comments) has ever indicated a rear disc past '79. Still, they made a fair few variants in a way. The frames are certainly different even between E models. The later ones, G and H etc. did away with the cross member under the seat above the guard... What is the frame number? I do recall there were a few new E model frames floating around a few years back...$90 each! Should have bought one, or two! SR |

Stoo if you quote the 2J2 number its definately a rear disk 78 model so there shouldn't be a problem . The problem is usually the bike being much older than the guy behind the counter at the dealership & it confuses them as the parts list may be only on the fish . But a lot of other late 70 early 80s had the same brakes (XS650 Special,RDs,650 4 pots etc ) have a look so your not ltd to one model for bits ! Stewross I posted some pics in Dave's bikes as I'm considering selling my 82 but I may have second thoughts as it could be a rarity with the rear disk( its definately stock & all the numbers match up , frame,compliance&engine ) . Its nos are 4F3-010634 , 2/82 . I was always confused with this as common sense would have the drums on the 1st models ? Anyway you can't beat them (I've now got 3 goers & I've got to choose which one to ride using the eeny meany method as I love them all !) cheers Dave.

Hi Dave, The frame looks like an early E model one...the earlier ones had a different gusset on the left with a front to rear raised ridge through the centre...and the early E frames also had overly strong rear left pillion peg mounts...with extra gussets at the top and in the centre of the tubes...both the E and F model swing arms had cast (or perhaps forged) rear wheel adjuster mounts...none of the later bikes have these as far as I am aware. As you say I can't explain the serial numbers of course... I have one of these frames sitting in my back shed. Both of my going E models are of the later E model frame type. Sorry to hijack your subject Stew... SR |

Stoo - Either year would have a front disc, and if I'm not mistaken the same caliper rebuild kit works for both front and rear caliper on the 2-disc bike. Probably the front/rear XS650 calipers as well. Thumperstuff in the US sells the kits of course.

BTW why did they go from discs to drums? It would seem to me hey were giong the wrong way with their development!

I would say styling basically...the front drum is a stylised copy of an XS1 650 drum...works very well really. As good or better than the standard original disc in my experience...Suzuki did something similar with their 400 Tempter in Japan. SR |
