V4 RR 2019 mod questions?

Hi Chaps,

I've had my V4 RR for a few months now and I'd like to make a few mods.

1. I'm not getting the feel I'd like from the rear shock (Sachs) and wondered what my options are.

a. get it re-valved and/or resprung,
b. swap it out for a different shock unit (Nitron, DDS, Ohlins, other)

2. I'd like to swap out the chain and sprockets and go up a couple of teeth on the back. Any recommendations on sizes and sprockets/chains?

3. Tail tidy - found a nice looking one by a company called J-Tech. Looks sturdy and well made (and only 29 quid). Anyone used these in the past?

4. Rear tyre size - I've heard going up to a 60 section on the rear can improve the handling?

5. The Leo Vince exhaust I bought is a bit on the load side. Any ideas on how I could quieten it down a bit?

Thanks in advance,

Cheers.

Hi,
Thanks for replying. It was helpful ;-)

The Leo Vince exhaust has no EXUP type valve so I can't refit the cables.
It has a baffle which I took out, packed with exhaust packing material and refitted, but I'm not hopeful it will make much difference.
I've put the original back on for now.

I've found a new Ohlins RSV shock online that will fit my RR but I'm just deciding if the spring is too stiff for my weight at 95Nm (The vendor says it will fit my bike). With my gear on and my back pack I'm probably around 90kg?

In terms of sprocket sizes, any ideas on what I should go up to? Just a couple more on the back maybe?

Thanks.

Lots of Renthall stuff in short supply at the moment,I think supplies from the factory have been disrupted.
