What have you done on your bike today?

That's a 749 Dark budget special - Ducati never made a Nero although Ducati UK did some A4 printouts mentioning a Glossy Black 999 pretend Nero limited edition bollocks :unsure:
He tells me the PO had all the plastics removed and had everything sprayed in a matt black and then new decals applied, ah well, each to their own. He even put crash mushrooms through the fairing 😮. Oh, and fitted wavy discs ffs, wavy discs are faster right ?
 
Rear suspension collapse? :unsure:
Yep, he was riding it, had just accelerated past a car when, in his words, it was like the rear brake had suddenly been applied with maximum force and seized on 😮, locking the rear wheel. In actual fact it’s the bush on the suspension linkage which has collapsed causing the suspension to sheer off its lower mounting linkage and the rear subframe of the bike make contact with the rear wheel.
 
Oh, and fitted wavy discs ffs, wavy discs are faster right ?
On the subject of wavy discs can someone please enlighten me as to their purpose? It seems to me by cutting out sections of the disc to make the ‘wave’ one is, in effect, reducing the braking area of the disc 🤔 thus impairing braking efficacy, arguably more so on these particular ones due to the whopping great big holes in them.

These ones look particularly

Copied and pasted from Google, can't say i agree with this but eh wtf do i know?? :)

  • Weight reduction
    Wavy discs are lighter than standard discs without sacrificing strength, resistance, or performance.

  • Heat dissipation
    The wavy shape of the disc creates a "seesaw" effect that prevents the outer part of the disc from being in constant contact with the caliper, which helps to prevent overheating.

  • Improved cooling
    Some say that the wavy edge design can disrupt airflow and improve cooling.

  • Performance
    Wavy discs can offer the same performance as a circular disc of the same size and thickness, but with less weight.

  • Appearance
    Some say that wavy discs look great and improve the look of the wheels on a bike
 
I don't know

Someone suggested this:

I believe it is to better scrape the surface of the brake pads, to help clean it. It needs cleaning, or scraping because brake dust and other muck can build up on the pad surface and reduce braking performance.

If they are so brilliant and all that why are they never used in WSBK, BSB and Motogp? 🤷‍♂️
 
They only use carbon discs in Motogp, no surprise when they kick out 270 BHP. Fucking insane but on track it makes sense but you can buy bikes close to that on the road, imo for the road it makes no sense!! 🤷‍♂️

AFAIK the main benefit of carbons is lack of fade, so like you said, no point on road bikes considering the extra cost

Wavy discs were originally developed for dirt bikes as far as I know, essentially to scrub off mud and shit from the pad disc interface. I would suspect they do very little on a road bike of that...... Apparently they look good to some

I'm surprised that Bimota don't use them. Their designer has an eye for aesthetics.

I thought they were to resist warping when hot. Many people fit them to Superdukes thinking it will cure a supposed warped disc problem that causes brake rubbing but that is more likely caused by the mounting surfaces on the wheel hub being misaligned.
 
My mates 2021 ktm .890 adv has developed the pulse too and it is very noticeable and un fixable. He is going to get some replacements, maybe wavies.His mechanic told him that one thing that can happen and is bad is when you are braking hard and come to a stop with vey hot discs and then sit there with the brake clamped on as it begins to cool. It cools unevenly and warps the disc potentially

A known issue in automatic cars but I think it is pretty rare now with thicker discs

My now wrecked 900ie and the 996 on having there MOTs they had both developed a slight fluctuation on the disc's. I took them off on both bikes and unbolted them and cleaned underneath on the wheel then put the discs back on unbolted and span them round and it sorted it out. So it wasn't the discs that where warped but some how shit had built up underneath the discs where they are bolted on. 🤷‍♂️
