Front brake switch

[Blue_SV650S]

Are trail bikes exempt from needing a front brake light switch for an MOT??

Hi,
iirc, if it was made after 1986, then for each working brake there should be a working stop light,

Just tape up all your lights, job done. All you need is a plate and a horn for an MOT. There's also no such thing as a daylight MOT - you'll get a normal MOT with an advisory saying that no lights were fitted at the time of test.

hi,
an advisory notice (or a note on the actual mot cert) stating that "the vehicle may only be used during daylight" or "not to be used at times of reduced visabilty" IS what most people refer to as a "daytime mot"

I pressume you talking about your WR, which do not have a front brake light switch.

Mine dosent have one, and its been through 3 MOT's.

Yeah but the Yamaha WR is a road legal bike, and it isn't manufactured with a front brake light switch.

So we are expected to modify the original bike to get it through an MOT ?

Hi

More likely that it isn't strictly road legal.

Lighting rules:-

Ta

Although my WR doesn't have a front switch (making it a bit dodgy that a dealer gave it a full cert before selling it to me!! ) I am actually getting the KTM up and running ... that too has no front brake switch ...

I am thinking that pressure operated banjo bolts are the easiest way forward??? ... shame I have to 'disturb' the brake lines to do so mind ... that generally causes a bit of a PITA

Hi

The pressure switches are probably the easiest way to go unless the master cylinder is shared with other bikes and is set up with a position for a conventional switch (possible if it is a Brembo m/c on the KTM).

Quite a few Italian bikes use the pressure switches as standard.

All the best

Just seen these responses ... but not before I had been out 'shopping'

As it happens I had picked a DRC pressure switch (like the one on the right) off the shelf at a bike shop today.

The threaded/banjo bit was a fair bit longer than the one that came out; but went in and sealed, so I presume it doesn't matter it was longer?!!?

Anyway .. it is all in and fitted, I checked with a multimeter and it DOES switch under pressure ... ... (can't check for real as the engine is off being fixed) ... but I have just noticed that under the price tag from the shop, the actual DRC label says 'Oil Pressure Switch # D45-71-282"

Will that matter?!!?!?

Anyway, the KTM banjo actually comes out the BACK of the master cylinder, so it fits quite nicely ... see pics of it fitted

Hi

Honestly don't know. While it wouldn't surprise me if the liquid makes no difference, I would expect a brake switch to need to put up with far higher pressures than an oil pressure switch (eg, 200~300psi for brake pressure, 60~100 psi for oil).

All the best
