Hi all

I'm a new member located just outside Dublin in county meath ireland. I have just bought a bantam d10. And want to achieve the look of a bantam trails bike. Without necessarily doing competitions / taking it off road regularly etc. I have no mechanical experience, but I’m looking forward to getting to know the bike and getting stuck in. Question - wheels and tire set up on a typical trials bike seems to be 18 rear and 21 front ? Am I correct in assuming I can just fit these new size wheels to my bike and buy appropriate trials tires for them etc. sounds stupid when I write it out, however completely green when it comes to this. Thanks

Welcome to the world of Bantams Singe.

You can get dual purpose tyres and knobblies for your 18" wheels, if it`s just the look you want and for doing a bit of rough. A 21" wheel deals with undulations better , that`s one reason Speedway bikes have 23" front wheels, helps when the tracks rut-up...when I last looked years ago. Also larger front wheel alters steering geometary. Two bikes I own(Yamaha TT500 &XT350) are designed to take 21" wheels, but none of my Bantams were designed to take a 21" front wheel.

Thanks blue - any idea we’re I may buy the dual purpose tires from ?

from what your say I’m assuming it possible to fit a 21 inch wheel to a d10?

Nice work Robbo.

Singe, ** Please log in to view **

that`ll probably be not much  dearer than what a 2nd-hand wheel would cost....if you can do your own wheel building.

Here`s a nice dual purpose tyre, not cheap though ** Please log in to view **

A cheap knobbly starts at around £25

Suppose it depends how capable you need it to be ? I've done my local lanes on a modern enduro and plan to do them again on my Bantam with 18" wheels and dual purpose tyres probably a lot slower but just as much fun 👍

Robbo - that looks cool, just what I’m aiming for - so he a raft of questions for you. Were did you source the mudguards, wheels, tires, seat. Etc etc. was the bike originally a road going version of the d10. Looks great. Thanks

Thanks for post Danny - I’m not sure I’m posting correctly ?? Do you have a photo of your bike for a bit of inspiration ?

Thanks blue - I have replied to you but pressed the flag button - so think my response has gone some where else. Anyway - had a look at both those links - they look promising so added to my ever growing e bay watch list thanks for that.

Hi - thanks for the photo post - actually just posted comment on another thread you started about your build - realized you probably had all the bits originally. Looks great completed. Any other mods planned for her ?

Don`t worry.

I`ve never flagged anything, but I`m guessing it`s to alert Admin to inappropriate content 🙂 Yes, far right, the "..as in to quote...and then you can always trim that down to focus on detail...if it`s a long piece, before compiling your answer and pressing submit reply.

I`ve run modified Bantams on the rough with 18" back and front and have a D7 with the kicked-up subframe loop to permit more rear wheel travel, by being able to set the mudguard higher. The top shock mountings can also be modified to be similar to Tiger Cub ones and longer travel shocks fitted.
