Title: Rear Sets
Post by: Max Headroom on March 16, 2021, 12:14:39 pm
Hi All,

Just wondering if there's any interest in having some rear sets made? I can model them and provide CAD files to a CNC machine shop, they would be similar to Rizoma but stronger, taking into account Tim's comment on side stand, and I'd spec better bearings as mine are already badly worn in just 3K miles. I'm suspecting to make this viable I'd need at least 10 sets, 20 would be better.

Cheers

For anyone interested, one of the guys from the Facebook forum is going to team up with me and we're going to give it a go. It will take a while but I'll post progress on here. Also we considering a billet aluminium swing arm which should be cool, I'd also look to make it belt drive compatible.

Sounds good, I've got one of the Flyhammer sprocket covers if you want to have a look at copying it?

OK, here are a couple of images of the first piece, the left side main bracket. I've designed it so it can replace the current Rizoma piece, for those just needing a stronger bracket. Please let me have any comments. It obviously can't be a direct copy of the Rizoma or a Sato unit.

Mmm...Problem is, it's too incongruous a style if all you want is a hanger. It will look too out of place IMO...
  My two-cents... :)

Hey Tim, I’ll post shots of the 3D print in position so we can see what it looks like and then if too incongruous I’ll adjust. I put plenty of cut outs in as I thought the original looked “blocky”
You can always buy the RHS bracket as well then they’ll match 😁

Note, I’ll also be modifying the gear lever pivot to be double bearing so it won’t wear out, like the original Rizoma piece.

Hi all,

Below are images of the 3D prints of the Rearset LH mount and the Sprocket Cover. I will be making some changes to the sprocket cover; I intend to make the windows maybe 5mm smaller and slightly reducing the height of the logo. On the rearset mount, changes will be around stress points, maybe smaller cutouts. Colour wise they'll be anodised black, with the logo left aluminium on the cover.

Please let me have any comments. I'm modelling the rest of the rearsets in the coming weeks and possibly production runs next month. Prices TBA.

NOTE: Tim made a point about the strength of the Rizoma LH bracket and having found both my fixing bolts bent I have to agree that it does not support the side stand correctly. If there is any interest, I will try and keep this bracket similar to the Rizoma one so anyone who just wants to replace this piece can do so. If no interest I'll depart more from the Rizoma design.

Cheers

Max

Sprocket cover- count me in.
Sold my Over rearsets, my ancient frame prefers the factory foot positions!

 Rizoma parts, of which a great many already have some, are all polished natural aluminium....
 I could live with this as a variation, if it was possible to simply forego the cut outs as indicated, and the  anodising....?




  They look great BTW.

I’ve been chatting with Nikk and he reminded me neither the rearsets or cover were anodised, so I’ll produce all parts natural aluminium and offer anodising as an extra. On the cut outs, I’ve got to do some stress work so they may change to being a bit of relief rather than cut through.

Is the sprocket cover from billet in one piece? The Flyhammer one is a 2 piece which i'm guessing cuts the costs.

Looking good.

Personally I'd say the MT logo should be a bit more subtle, with less height from the main body of the cover, but otherwise great!

Re-flyhammer; New cover is one piece from billet but should be around the same price.

Re-logo; I’ve already reduced it to 3mm

So, I too am happy with the standards but tell me, with the solid mounting, how much more are you feeling through the feet?

Hi Graeme,

Personally I've not noticed an increase in vibration from the rearsets, but there must be some increase, maybe boots absorb some?

  Its such a long while back I did this. I have 50K miles with Rizoma controls, and not needed new bearings at all. What I do I remember is being pleased with the increased tactile feeling from the rearsets and decent levers ( rizoma )...Im fairly sensitive to vibration, having held a chainsaw in my working life for many years - the solid mount rearsets do not give any problems in this regard....

Something else Id like to put out there @Max Headroom; if the actual footrest pegs, the bar your foot rest on when using them, if these could be a replacement to the originals, that would be fantastic. Mine are polished and smooth after 50K miles, and it's becoming an issue to keep your feet from slipping off, especially when wet....If you didnt insist on styling yours so differently from the originals, but anyway made them fixed in the same way, a pair could be easily bought separately, to replace worn originals....?
  I feel like a lobbyist for Rizoma.... ::)

Jesus Tim, your list just gets longer and longer :) I'm just working on the design of the lever/footpeg mounting so I'll try stick to the original interface for the peg so you can use it.

Keep you posted.

Hi all, just thought I’d give you an update on progress and share a few more photos as things move forward. What started as me is now firmly a “we” as Andy from the Facebook group is facilitating machining and Nikk from here, Facebook etc is coming in too.
The sprocket cover has been a pain to design but I think when you see the pre-production piece you’ll agree it’s worth it. It’s machined from billet 6082t6 aircraft quality aluminium. We’re just deciding on the anodising. We’ve also done a 2nd 3D print of the rearset bracket as there were a couple of tolerance issues and we can now move on to a pre-production piece.
Andy spotted a little problem in my plan and that is the Yam/Rizoma sprocket cover was only for use with the racing rearsets, so the plan now is to do a 2nd one that will work with the standard footrests. We’re also thinking of another cover for the opposite side to remove that piece of crap plastic too. Please let me know your thoughts.

 What about doing a fuel filler cap Colin...?   ;D
Title: Re: Rear Sets
Post by: Max Headroom on May 17, 2021, 03:48:57 pm
You'll notice how I blatantly ignore Tim's comment on fuel filler cap. :))

Ok just wanted to update everyone who isn't on one of the Facebook groups. We thought it would be good to do a version of the sprocket cover for those who don't want to fit rearsets. We also thought it might be nice to get rid of the piece of plastic on the other side so there will be 2 offerings for this side; one with another MT logo so you can have MT logos both sides or one matching the 2nd bit of design work on the sprocket cover. Cost of the sprocket cover will be £180 plus P&P the other cover is TBA but it will be a fair bit cheaper than the sprocket cover. Hopefully have some made by early July.

Morning!

Any updates on the rearsets and cover?

Apologies for delay with the project, I’ve been moving home back to wonderful Yorkshire. Lots of work to do on the new house but I’m meeting with Andy who’s doing the machining next week so I’ll give you an update then.
