Anyone know what other bikes use the same UK spec Kotto headlight?
I can start to answer this now.
Consider the headlight in three parts...
1) Shell
2) Rim
3) Reflector/Glass
1) The shell is unique to RD250/350LC.
Over the years there have been many pattern headlights, and on some (the one I have for example), it is identical to the Yamaha/Koito one in all but the Yamaha embossing on the back.
The current pattern headlight, which seems to be the only one available from all sellers at £27 through to an outrageous £50, has a glossy shell made from brittle plastic which is thinner than the original plastic. The holes and clip are in slightly different places. there is no upper hole for the wires and connectors from clocks and indicators.
An original OEM rim should fit, perhaps with a bit of easing of the holes, but I have not tried that particular experiment yet.
2) The rim is unique to RD250/350LC
They are as rare as Unicorn doodoos in unblemished form, with good chrome and no roadrash.
The rim on the currently available pattern headlights is made of flimsier metal, and the internals are of a slightly different design. The clip, and the two mounting holes are not quite in the same places as the original rim, so it is not a straightforward swap into an original shell, without modifications to either rim or shell.
3) The Reflector/Glass differs from market to market.
European markets have E4 cast into the glass on the front, and have the number 997-16119 printed on the back of the reflector. They also have a metal dome mounted in front of the bulb, inside the unit.
I assume it dips to the right.
The UK, and other left hand drive markets, (Japan, Singapore etc.) has no E4 designation and has 997-16120.
i assume it dips to the left.
Right hand drive markets, (Canada, Rest of the world) has a similar glass front to the UK model, but has no pilot light. They have the number 997-16121.
I assume it dips to the Right.
There are a number of bike models which appear to use these Koito reflector/glass units.
I can confirm only two...
1) Yamaha RD250/350LC (Obviously)
2) Yamaha SRX400/600 (I bought one, the unit is identical, and is numbered 997-16120 for the UK model.)
The rest of the list, which i assembled looking at pictures on t'intrnet is as follows.
Some of these bikes are US only models, so will have the US spec reflector/glass.
- YAMAHA SR400 SR500 SRX400 SRX600 XJ600N
- SRX600S 1986 600 SRX600 Street
- SRX600SCal 1986 600 SRX600 (Cal) Street
- XJ1100J 1982 1100 XJ1100 Street
- XJ750K 1983 750 XJ750 Maxim Street
- XS1100SF 1979 1100 XS1100S Street
- XS1100SG 1980 1100 XS1100S Street
- XS1100SH 1981 1100 XS1100S Street
- XS750F 1979 750 XS750 Street
- XS750SF 1979 750 XS750S Street
- XS850G 1980 850 XS850 Street
- XS850H 1981 850 XS850 Street
- XS850SG 1980 850 XS850S Street
- XS850SH 1981 850 XS850S Street
- XJ550(1981)
IMPORTANT NOTE:
I cannot guarantee that this list is correct, as I have only the veracity of the pictures online to go on, and they could be misidentified or misnamed.
I have an XS1100 headlight in the post, so I can update the verified list when that arrives.
I hope this info helps someone, and if anything is obviously wrong, then speak out and get it corrected before anyone wastes money on attempting to build out the verified list.
Cheers
