my 2000 UC had a mustang and backrest when i bought it..i rode for several miles without the backrest then reinstalled. OH YEAH>>>> got to have a back rest.....
I have the Mustang 17.5" super wide touring solo seat with removable backrest. ($500 seat!) Now, I do not have a bad back but I NEVER EVER use the backrest. If buying again, I would buy without as it's a $200 upgrade. I've tried it a number of times and it's just not comfortable for me. JMHO
Not sure why but they hurt my lower back Tried a Firehousecustoms fixed model and when that caused me low back pain I tried the adjustable Mustang. Same thing.
I like mine when highway humping on long days. I don't care for it when doing the twisty thing. The mustang version is on and off so quick I just switch it out when the urge hits.
i had both but i did not like it in town. on a trip i can make one from the luggage. i changed it out to the regular mustang. it is more a personal and medical opinion.
I have had them on my last 3 bikes (all Mustang) and absolutely loved them. I do remove it when riding around town, but for the long haul, nothing better.
