I use Monroe shocks from a Bagheera on my Murena 1.6
They are bit longer but thats not a problem and they work just fine.
Never heard about JYB but for 90 pounds you could take a gamble.
But the front suspension is pretty simple when it comes to shocks.
You should be able to make almost anything fit
