Glad you raised the subject, I've just bought these Avon Roadrider Front 90/90-18 51V / Rear 100/90-18 56V. Got a voucher which made it £107.94 delivered  . I need a 100/90 18 with a tube for my CB250N.   this may seem a strange question (I’m a strange person) but how do they compare weight wise with the tyres I remember back in the day, as I’v mentioned elsewhere in this post I’m blown away by how light pilots are and for me this is a major consideration. the road riders are probably my second choice as they seem widely available in the right sizes and speed ratings. either that or I’ll go out and buy some square deaths (avon sm’s are still available  and have you seen the price?) and have the full retro experience |

buster the last time i got my knee down was last year when I fell off it in a layby I got my foot down as I came to a stop but there was a bit of a banking there my foot slipped back under the bike the front wheel slid out the other way (dirt layby) and over we went (ouch) I broke my foot in two places and still had to ride another five miles home changing gear was different and painfull but I got there eventually  |

I have had a look at these and I used to run me33’s and me99’s on my old ninja (really no choice cos of its 16” front wheel) and the metzeler range are good tyres. thing is though I really fancy the pilots because of the weight (lack of it) I got a 180 and a 120 for my kwack and couldnt believe how light they were and anything that ditches unsprung weight can only be good for handling. Good call on the weight, I'll freely admit that I didn't even give it a thought. Though i guess the differences in tyre weight are fairly inconsequential if they're going on a b*stard heavy comstar wheel?! Then again as you say, every little helps! |

I’m really only fretting about weight because mines got 250rs spoked wheels (when I ever get them built) |

Potentially getting off topic here, but why did you elect to use RS wheels rather than converting a comstar? (as per: motosynthesis.blogspot.com/p/products.html). As an RS rider I find the rear hub to be the most irksome thing about the entire bike, the cush drive is awful, no "cush" whatsoever and the sprocket retaining circlip mechanism perpetually finds a way to be floppy, despite machining custom spacers etc etc... |

I agree about the cush drive though had old hondas in the past with much the same set up and theyre a bit of a nightmare, this though is another reason for seeking out a light modern tyre, I’m also thinking hard anodised rear sprocket eventually all to keep the drive train as easy going as possible. in theory it should all help, in the real world it probably wont make the blindest bit of difference... |

How about a comstar hub spoked to the RS rims?! best of both worlds, cheap alloy rims and a decent hub with spacers that already fit the swingarm, everyone's a winner!

I honestly think it would be a massive expense and very difficult to do, how would you get a drill or milling machine in to machine the inner hub? |

I'd be into bolting on some laser cut flanges as below!  |

Whilst waiting on my 250 getting MOTed, the Dunlop book suggests K82 for the RS, with the option of TT100 if you wanted a 4.10 on the back.

bit more looking around on this one and I’m really holding out for the pilots, what I’v worked out so far is that I’ll have to pair a metric 90/90/18 front with an imperial 4.00 18 rear but I think I can live with that, it just seems strange to me that michelin dont list a 100/90/18 rear, still I suppose thats our kermit cousins for you

Just reading though this for the first time tonight as I am trying to see what the mostly now defunct 3.60 19 front tyre as fitted to our CB250/400N equates to in new money. I have recently tried a spare wheel with a 100/90 19 on my Hawk (o.e was also the 3.60 19 as per the SD) but to me it runs too close to the mudguard. It clears but just does not look right.
Therefore I am assuming that 90/90 19 is the closest to the 3.60 19. (P.S, you've all stated the front as being '18 inch' unless I missed something?).
