Sprint Triumph Sprint St 955i 2001 Questions..

No problem. Nitron definitely offer remote preload adjustment and I'm sure Maxton will too

Ohlins are nice but you may need to factor a rebuild into the oeuvre depending on the mileage it's covered. I put ohlins on my last two bikes and really enjoyed the improved ride but their shock for the 1050 is just too expensive

 

Hi - nice Sprint, mine's a blue 2000 (but a bit more travel-stained than yours seems to be!).
Previous owner of mine was a big lad and took the bike around the Med with his girlfriend and lots of luggage (panniers/top box/tank bag/bungees), he just wound all the preloads up and didn't seem to have problems grounding anything.
Is the alarm a Datatool Veto Evo? Mine's got one - the user manual (and other docs) are here:

You turn off the movement sensor by pressing the 'triangle' button, or put it into service mode (aka 'valet mode') for things like replacing the bike battery - but maybe you've got something different fitted 'cos a Veto Evo would need it's internal 9v cell (that stops it dying terminally if the bike battery is disconnected) replacing by now.....

 

Depending on the state of your back end you might find

worth talking to.

 

A Haynes manual is always a good start. I added Oxford tour grips to my 1050, and can recommend them.

Ebay may source used rack & box, but I went with Givi, and added the high-level brake lamp kit. I've also added bits like Scottoiler, sat nav, phone case & charge, dashcams, volt & amp meter, air temp meter, alarm, led headlamps, screens. Plenty can be done to keep you busy over winter.

However, I understand that stock bikes retain value much better than customised, so you may wish to bear that in mind.

 

Wouldn't worry about loading it up, I've been touring with the wife on the back and fully loaded, without any problems.
If you are worried, just give it a bit extra preload.
