Does anyone know if there is any physical difference if any regards Saloon 17" spacesaver and 17" Tourer spacersaver both have slightly different part numbers. Part No. 06421-TL3-305 for Saloon. Part No. 06421-TL6-305 for Tourer. I can't see the stud spacings being different or the rim itself, I think it may be just the polystyrene insert & kit may be slightly different across models, hopefully someone on this forum can answer this query. Will the Tourer Spacesaver fit the Saloon can any one confirm this would be appreciated.
