Pretty sure steering stem is longer (TS 185 same length as TM 250 or RM 125S ) and fork legs a bit shorter .
Legs are same dia 30mm TS 185 has bigger hub ( same size as TM 250 or RM 125S )
So it all interchanges except triple clamps wont fit in TM frame without shortening stem .TS bottom clamp is steel with welded in stem .
