Old Staintunes fitted with intermediate DB killers, not too loud and not too quiet. The next size down in DB killers make these homolgated as per the ADR plate on the inside of each muffler.

My bro rode the bike today and also liked the ergos and felt comfortable with the tyre and handling characteristics. It was good to get feedback from a rider with better dirtbike riding credentials.

Running Pirelli MT60RS 120/70/17 & 160/60/17. May try Metzler's new Karoo Street tyres in 120/70/17 & 150/70/17 or 170/60/17 which are nearly a hundred bucks cheaper than the Pirellis and over a hundred less than TKC 70's.

Will they do a pair deal on a narrower rear with a 120/17 front?

No special deal I can see, but my local Yamaha shop looks after me.

For some reason Continentals are incredibly expensive here, regularly 100+ bucks more than any other brand. A mate's Tiger 800 came with TKC70's, but although very impressed with their performance he looked elsewhere for replacements. With a 19" front, he saved 150ish on a set with another brand. The TKC 70's were great in the wet.

Metzler recently came to the party with the new Karoo Street providing a 17" front. Before that only 19 and 21 inch Karoo fronts. There are no Karoo Street 160 rears, just a 150 and 170 each side at ten bucks more for the 170. Strange they have a 170 instead of a 160 as I thought 170's were being phased out. The Pirelli MT60RS 160/60/17 looks like a 150 on the Ducati Brembo 4.5" rim. Anyone know if Metzler are on the fat side like Dunlops or more like Pirelli and Michelin?
Before the Karoo Street only Avon (Trailrider), Continental (TKC70) and Pirelli (MT60RS) provided a front 120/70/17 dual sport tyre for our market.
I cant get the Michelin Anakee and Dunlop Trail range in a 17 front tyre. That was quite frustrating as Michelin is my go to mfr, but no 17" fronts. The Anakee 3 range has a horizontal paddle shaped tread pattern which makes me think of sand drag racing.
The US tyre range and prices make me weep. Economies of scale I guess.

...but we can't get a race rain for a 5.5" rim.

I want to set up the SS I bought as a wet bike, and would invest in full rain tires, but I can't buy one here.

That's amazing.
I heard racers are using the Pirelli MT60RS Corsa's for rain tyres in local SBK. 180 rears.

The K&N barrel filters and bags that protect them. The code for the bags which will also cover RU 1750's

Thanks to Speeddog for putting me onto the K&N site that lets you select parts by dimension, code and model. Bloody handy.

I found some tuning notes after relocating.

The pod filters in question are K&N RU-0800's. 102mm long, 89mm in diameter and have a short flange with 62mm ID. The short straight flange lets the pods clear the tank and gives air a straighter path to the carb bellmouth. These are better than the RU-1750's because they have a molded in bellmouth or V stack radius for a better transition from the filter edge to the flange, whereas the 1750's have a sharp, right angle.

Just something to consider with pods.

Was hoping for Michelin's, but that's an option if the 185 doesn't foul the chain.

It'll be close as Dunlops can be a little plump for the size.

Something like this. On the slimmer side too for chain clearance. There may be a Corsa version still available.

That link goes to an on/off road tire, not a rain.

[koko64]

The stickier Corsa version gets used as a race rain tyre. Worth an enquiry.
