TS185 fork dimensions
« on: November 20, 2017, 05:36:35 PM »
Can anyone supply the following  dimensions please from any 77-78 TS or DS 185 (for US/Can readers)
Take fork measurements with either fork off off bike or make sure the fork is fully extended when still on bike (jack the bike up so front wheel is off the ground)

as per photos
1 - axle hole center to top of alloy outer tube/slider
2 - top of the slider to top of the chrome inner (dont inc fork cap)

Triple clamps spacing when properly fitted
1- bottom height
2- top height
3 - gap in the middle

Thanks



Wanted - 1978 TS185 frame

I thought er185 were all leading axle fork and the 2 I found on epay are also but the Aggie bike tf185 are straight leg forks like in your pic or the same as ts185l| m and a models

ts185 A are almost the same as the L and M but have a larger internal capacity.
 B model were still non leading axle The C model(ER) were the first leading axle.

Why not do a part # comparison to see what RM model shared those components as there probably arnt a lot of B models around.

 without looking very hard that triple tree looks very much the same as the L and the M stuff I have

The pics posted are TS250B parts but for this purpose do the job.
I hate to correct you but 78 C is not an ER and are not leading axle.Australia had 2 different 185 models in 79. An N model with 32mm leading axle forks and an ERN with 33mm leading axle forks.
I don't actually need these parts just the dimensions for 77-78. 77 are different to 78 mechanically but i would expect the lengths to be the same. I would not expect any of these 30mm 185 forks to have any parts in common with RM's but the TS250 does share many parts with 76-77 RM

TF185 forks will probably be the same as 78 i would think. The inner tubes are same part number as 78 185 but the other parts are different. I dont know if the change is a dimensional one or something else so at this stage safest thing is to stick to the 77-78 TS dimensions.

I just checked TF numbers against the DS and yeah TF uses the DS damper rods, black outer tubes etc so TF forks would be same dimensionally as TS. So yeah if anyone has some TF185 forks to measure then those would be OK too.

Sorry you are correct The C is non leading axle,

 Do be careful with part# as Suzuki list the exact same # for the stanchion for the early TS185 TS125 TM125 and TS100 but they have different internal machining to cater for the preload caps on the 185. Other measurements are the same. I wouldnt put it past them to do the same on later models.

Thats the difference between 77 and 78 inners too. The fork caps are different thread heights. At this stage i think they would be same length so 77 or 78 dimensions are fine.
