That has been what I have thought about - DNA has a wheel that says it will fit the FXST/c & FXDWG - 21x3. I think they have the same front end as the FXSTB night train. I would really like to go to a 3" wheel if it will fit with my stock fender. I think the ride & looks will improve. KC International has either the 21x3 or 21x2.15 for $425

 

 

Ok this is a great thread I really want a bigger front wheel ans tire.. my only question is spacer size for everyone that went with a 3.5 and does the stock rotor and brake have any clearance issues

 

You just need to make sure that if you need new spacers for a new wider wheel.
They put the rotor in the same position in relation to the fork leg & caliper as the stock wheel,
If that's done, it should work just fine.
I would be more worried about fender clearance.
The narrow fenders on bikes after 07 are closer to the tire than older ones and might not have enough room at the edges to clear a fatter tire.
Especially if the new wheel has to be moved a bit sidewise to get the rotor aligned properly.
In which case a new aftermarket fender might be needed as well.

 

That looks sick! I want to run a wider tire on my train. I have a JJ Doom rim up front but, I don't know how wide it is. The 21" came in 2.15 or 3 I think. I'd like to go with the 120/70 but I don't want to have to buy a new rim. I have a brand new 90/90 21 Dunlop that came with the bike but I'd much rather sell that and buy the Metz. I'm also running an aftermarket wrap fender and it looks like there's plenty of room in there for more rubber. My only concern is if the tire will fit the rim.



That's the best pic I have of the tire/rim up close...

 

That's a 120 on a 3.5" rim on Chuck's bike. I ran one too. Much better handling than the 90.

 

HI there, I need your help please.. What front fender did you buy to fit the Night Train? I have intentions of increasing to a 21 3.5.Any mods needed.. Regards
