Devon TRF Group Forum

Well,

The story started a year or back when I decided to flog the HD and get something different......well SWMBO wasn't impressed as she likes going out on the tractor now and again so the idea was shelved . A month or so ago I took a shine to a Trumpet Street Triple in Bridge as it looked like a fun thing to blat about the B roads on and I quite fancy something 'fun' to ride on the tarmac but (no disrespect) bridge ain't the sort of place I'd buy a bike, it was tooooo much  the HD would have to go to fund it and SWMBO would not be a happy bunny

Well this weekend I went up to Wiscombe Hill climb and watched the lads and lasses hooning up the hill on a wide range of machines including......KTM's on BIG SLICK TYRES !!!!!!

Well that was it - I had my answer, whack some super moto wheels on the Katoom, Then we keep the HD and SWMBO is happy and for minimal (ish) money the beloved Katoom becomes 3 bikes a laner, a B road 'sratcher' and if I get brave enough - a hill climber ?

Lath had a set for sale that I was kinda thinking about - but after Wiscombe I just had to get them - so picked them up on the way home that very day

We weren't sure they would fit (well lath was sure the back one would) but did 'sort of' try the front one in the bike and it looked about OK so the deal was done.

Monday night I stuck the rear in to see how it looked :-

Now got the front in - this wheel is a non KTM hub laced to a KTM rim (back is all KTM) and uses a smaller older KTM spindle (I think) it came with loads of different spacers and some 'sleeves' to insert into the bottom of the fork legs to 'downsize' to take the smaller spindle.

It all fitted fine but I have had to 'fiddle' about to get the wheel aligned and get the caliper (the wheels came with a new 320 mm disc and cliper bracket) all lined up.

So next job is to go see 'a nice man' to get one of my spacers machined down by about 5mm (and Lath its the one on the disc side that I need to do - hence my puzzled looks Sun eve as I could not work out how it would be the other side to 'push' the wheel to the right).

I found a 'temp' spacer which fits bang on so have a 'pattern' - below the long spacer needs to be 'cut back' to the length of the short one.

So once thats done next job will be to whack both wheels in, sort the chain and experiment with the sprocket sizes/gearing - so any suggestions on what size I should run would be apprectiated.

The rear tyre is good but the front will need changing soon so not having a scooby about super moto type things I would apprciate some suggestions for some super sticky rubber as well

Can't wait to get it all finished and try it but will have to wait till next week as I have to get 'dirty' this weekend and gotta get that spacer sorted.

Cheers Harty - noted this comment "now i'm driving 14-43 but the bike goes too fast with it (I allready reached 105mph and it was still going...)"

 

The wheels came with a 38T rear and I have a 14T front, having read up now I think I may get a 13 front to try with the (new) 38 rear which would equate to a 14/41 or as nick says 15/45? (as I don't think I could get a 15T on the front anyway though I do prefer a larger front).

Am i right chaps does 13/38 = 14/41 = 15/45 or there abouts? 1 tooth on the front = 3/3.5 on the rear?

 38/13 = 2.92

41/14 = 2.92

45/15 = 3.00

SO all combinations offer equal (ish) gearing.

Quick update

Been to see Tim and the spacers now the right size - cheers mate

Before.....

And now.....

Jack - what tyre pressures you running mate?

 And hows the 14/40 gearing?

(sorry for all the questions but its all new to me )

Great - got a new 38 on my new wheels so I'll give that a crack then and maybe 26-28 psi

Cheers bud

Cheers Lath.....going to stick with the 14 front, but not sure about that 38 rear having spoken to you chaps, think I need a few more teeth on the back but not as many as the 52T on my enduro set up....

28 PSI is what I was thinking so you confirm that also.

Job done, tested this morning hell its quick gotta change that 14/38 but a nice man just rang and has a selection of chain, 44/45 T rears and a 15T front so plenty to experiment with

Top end mate - could hardly use top gear.....needs gearing down, so going to try a 15t on the front 1st and if that still doesn't work I have a 44T rear that I can try with the 15 or pair it with the 14 I have on now.

 Dont bother with 15 on the front will make it worse! what speed you toping out in 4th cos with mine at 14-38 its revving out in 4th at 60mph

Feel I have to join in here too cos I got meself a set of SM rims for the 450.

Sprockets are 14/44 (what it came with) Seems perfect to me on the black stuff - good pick-up, front end happy (i you want) and enough top speed not to need to top it out.

Right, next SM topic - SUSPENSION! My KTM is set-up uber soft for laning, everything backed almost fully off (soft), how do people have their SM's set-up for the road? Harder obviously but how manay 'clicks' in or out for each of the settings? (please also indicate bodyweight as this will make a difference - unless you're too ashamed! )
