YBR exhaust

[dansidi]

Suggestions please for an after-market exhaust system for a YBR125 (2010).

Hi,

The exhaust downpipe on my YBR125 (2010) has always looked very rusty since I bought it 2 years ago and now the rust is flaking off if I touch it. The downpipe is still intact with no holes or cracks but I guess a new one will be required soon. I also have a couple of cracks and scratches on the crappy plastic exhaust silencer (stock Yamaha).

So my question is: what good quality after-market exhausts are available for a small bike like a YBR 125? When I look at exhaust brands, they all seem to be for larger bikes.

Also, what can I do to protect the pipe from rust? I have used ACF50, but not regularly and I do ride in all weathers on the salty London roads.

Many thanks

Why not grind off the rust then paint, might save you some money. Black enamel looks alright if done properly.

IXIL make a 2 piece stainless steel exhaust system for the YBR, currently discounted at just under £240

Or you can wait to see if the slightly cheaper Motad system ever becomes available

Both will most probably outlast the rest of the bike.

Has the bike been kept outside all of its life? And then soaked in saltwater?

I just find it hard to believe that a 3-4 year old bike would have downpipes rusted through!

I don't really think ACF will stop is rusting either. Autosol or similar will be best. Buy some wirewool and autosol and use some elbow grease to get the things shining. I'd would be very surprised they they would've rusted through.

Just can't imagine a relatively new japanese bike having downpipes made of cheese...

EDIT: Don't really why I mentioned ACF won't stop rust... Must've though it was something else!

Exhausts are fairly cheap on eBay, unable to Link you as I'm currently using my phone with Its crap browser

You could either buy a aftermarket exhaust £100 plus or buy a standard one the same as yours from £50 plus. Being realistic about performance it's not really going to give you a performance gain, it will just make it louder.

Also when come to sell the bike it will be easier to sell with the standard exhaust.

If the Yamaha original is only £99, I'd be getting one of those without a doubt. IMO when a bike is tuned for a specific power limitation then the fueling and exhaust system shouldn't be played with. Just my opinion of course.

On the stock exhaust there is a 'breather pipe' connected. Having looked at some alternatives, some exhaust systems do not have a breather pipe connection.

What is the breather pipe for? Is it necessary to have it connected?

The description on this item on eBay states "This exhaust will fit straight on how ever there is no receiver for the breather pipe that comes from the crank case unlike the original exhaust pipe. Its no problem to run the bike with the breather disconnected or blank the breather off.Your machine will run with no issues if this is done."

Should I trust that? Is it safe?

Thanks again.

The pipe introduces air into the exhaust to dilute the noxious gasses to enable the bike to meet current emission regs.

If the bike isn't tested for emissions then the connecting tube is not required. Currently the UK doesn't test (although Spain does!).

PS
someone should tell them that the tube comes from the airbox - not the crankcase breather, although any fumes not recirculated via the inlet manifold could end up in the exhaust.
Not having the tube connected to the exhaust obviously removes this option.

DO NOT attempt to block off the crankcase breather, just follow the pipe up from the exhaust and put a bung in it at a convenient point nearer the seat and then remove the excess (visible) dangling pipe.

Thanks for the info, Rik.

Much obliged!

YBR exhausts rust, sporty pipes are all around £250.

Put a wire brush attachment in a drill, buzz the whole thing over back to bare metal, then respray using an entire tin of techcote high temp matt black. Comes up like new and will cost you a tenner for the spray & grinder head. I did a little bit of a guide on here showing how to do it.

Should repeat this process every 6-8 months if using in all weathers & wanting it to look mint.

Hi Mark,.

In the end I decided to grind off the rust with the sanding wheel (pictured above) and then spraying it black with some VHT paint. Looks OK and I saved a bundle.

I did crack the plastic heat shield bit on the side, but I don't care about that too much. So be careful if you handle the exhaust - it's heavy and the plastic is brittle!

If I had the money, a Leo Vince would be my choice.
