Britbike forum Forums British Motorcycle specific Brands Triumph bulletin board 1967 T100R Daytona tanks

I received an inquiry today from a guy restoring a '67 Daytona 500. He wants to know if those bikes had tank racks, or not?

Problem is: I have photos of five original-paint tanks, only ONE of which has the screw holes for a tank rack.
It's obvious the racks were eliminated at some time during production, but when? What's the latest serial number bike that had one?

Does anyone have an ORIGINAL, unrestored '67 Daytona, with a serial number later than H55250?
Rack, or NO rack?

Thanks.

The 1967 & 1968 parts books (from H49833 & H57083) show the rack listed for the T90, T100S and the T100T, the tank is listed as 3 gallon capacity so maybe these were the home market models? They also show the 2½ US gallon tank listed without a rack for the T100C and T100R.

So without an original bike to look at the parts books suggest that throughout 1967 UK models had the rack fitted and US models didn’t, my money would be on no rack if it’s a US fuel tank.

I have a 3 imperial gallon tank although I don't know what year it would have been, probably later than 67 and there isn't any holes for the rack. It is now on my '70 T100S cycle with the 67 Daytona engine so may not have fitted a 67 but would go on a 68 frame.

Hi All,
'67 was when Triumph changed the C-range frame and fuel tank fixing to be similar to the 650's - frames look similar and the tanks use the same 3-point fixing (two at the front, one at the back, although C-range tanks are still shorter than B-range). So any '67-on tank fits any '67-on frame but won't fit a pre-'67 frame nor will a pre-'67 tank fit a '67-on frame.

As Chris posted, '68 still lists the tank rack for UK & General Export tanks, '69-on doesn't ... although I could mess with eveyone's heads by posting unqualified that I've a '73-on (no top seam) 3-gallon tank with Cycle-thread holes for a rack ... in fact, it's a police-bike tank, the 'rack' mounts are for a radio ...

The one with the screw holes is definitely a US-market tank?

Both https://www.triumph-tiger-90.com/index.shtml and Triumph Tiger 100 And Daytona echo what Chris posted, no racks on '67 US-market tanks. None of the '67 US brochures or ads. on classicbike.biz show racks?

Aiui, the decision was made to leave racks off US-market tanks after Triumph(?) was successfully sued by a rider who slid up the tank during a collision and bashed his 'nads?

Regards,

Of the photos I have, all definitely have the '67 T100R blue-and-ivory color scheme, so all look alike in that manner.

All are also the smaller tank used on the American models, but now I wonder if the one with the mounting holes for a tank rack may be for a
British home-market T90?

Did the T90 model use a smaller tank than the home-market T100T? The tank in question doesn't appear to have the recessed areas in it's sides
for the knee grips like I see on T100T tanks.

(I'm familiar with that "racked-my-'nads" story. Moral is: wear your PANTS when you ride!)

Hi,
Uh-uh; unlike the 650's, (apart from '70) Meriden issued only one C-range parts book per year, covering both US and UK&GE versions and their different parts. https://www.triumph-tiger-90.com/index.shtml advises Tri-Cor issued bulletins in '67 (67-5P and 67-6P) listing which parts in the Meriden '67 C-range parts book weren't fitted to US-market bikes.

So, unless either of those bulletins lists a different tank for any specifically-US T90's, the parts book WYSIWYG - i.e. same tank as T100S's and T100T's (except the T90's was painted Hi Fi Scarlet instead of the T100's Pacific Blue).

Hth.

Regards,

My very early 1967 Triumph T100R has NO rack

Stuart, NO T90 bikes were imported into the USA in 1966 or later. They aren't listed in the USA parts books or sales literature.
I have ridden Triumphs since 1967 and have never seen a T90 in the USA. So, I had to guess and ask about the T90 tanks.

I have seen two U.K home-market T100T tanks, and they are of larger capacity than what we got over here.

C.B.S., thanks. Now I can tell the fellow ANY 1967-72 T100R tank is what he should find.

Yes exactly

I do know the trims changed on the T100R tanks 1967-1968 and 1969 - Later

The shape is the same, one uses the hook, the other the stud FYI

Hi,
I thought that was probably the case - it's what triumph-tiger-90 shows too. I assume the only way a T90 would be in the US now is via Canada?

Officially, 3 British gallons vs. US tanks' 2 (2.5 US), although both take a little more in reality.

Also you noticed the UK&GE C-range tanks have only one tap outlet? The corresponding 82-1717 tap has separate main and reserve plungers.

Hth.

Regards,

I had a 68 T100T. Aquamarine and Silver. UK&GE. It had a tank rack.
