51mm slip on.

[0281-E Stuart]

Evening Chaps!

I'm in the market for a 51mm slip on.

There's plenty on eBay, and around the web.

Was just wondering if anyone could suggest anything from a reputable manufacturer (has to fit my Adrenaline, under the seat) so that maybe I could see a slight improvement in how the bike breathes — not looking for any drastic power increases, just a different tone and look.

A power increase would be a great bonus!

Many thanks indeed!

Is 51mm not a bit big?

You may be right...

For some reason I was under the impression it was 51mm.

They seem to make an adapter, think the pipe is about 38mm.

Thank you for raising that question.

They look great, they claim a power increase of around 4.5bhp in dyno testing.

I imagine this is true for the larger capacity bikes: 600's, 750's, litre bikes and inline fours etc.

With a bike running around 11bhp, is it even worth considering changing the exhaust?

Interested in one size up on the main jet and a slip on.

Cheers!

Wouldn't do it for power, but I'd do it for noise

Haha, yep.

Will pull the trigger on one soon and hope that my insurance company doesn't go into meltdown when I declare it

Hmm... Doubt you'll get anything noticeable on a 125 without other heavy modification.

Best bet is get a dyno readout (going rate is £30-60) and see if you're running lean before fiddling with jets and stuff.

Thanks for the advice, laughing at the idea of my bike on the dyno, L plates and all.

I am rather happy with the power, I'm light as a feather and have never had any problems!

Just feel as time goes on I may want to begin to tinker. As long as I declare it, and it is all legal — I can't see a problem!

Worth a look at Pipewerx as well. British made, well built and won't break the bank. Can't guarantee they do one that fits yours but they cover a lot of models.

Smashing, thank you for the recommendation.
