I would think that your issue will
most likely be something along the lines mentioned above, Old Prof, but (and note that
any of the suggestions offered in this thread should apply to
ALL years/models of Spyders fitted with OEM cruise control, altho in
this instance, the specific speed may vary) just in case any of the following helps... What revs are you pulling when you try to select Cruise Control?? :dontknow: I ask this cos I had one fella here in Oz come to me with a similar concern; he told me he just couldn't get his RT's Cruise Control to engage at anything but Freeway speeds!! :banghead:
In an effort to work out what was wrong, I took his bike for a ride and had
No issues getting it to engage whenever
I tried, even just cruising around the block at about 30 mph -
for me, it worked fine! 
I thought that meant his issue would most likely be the brakes thing; probably meaning that
before he got out onto the Hwy, stretched out, and put his feet on the Highway pegs that he loved so much and then selected Cruise Control, he might be unaware that his right foot was lightly touching &/or moving the brake pedal juuust enough to stop Cruise from engaging! So I followed him for a bit as he rode to check that and see what his brake lights were doing - it didn't take long to work out what the problem was, and it
WASN'T his brakes!! :lecturef_smilie:
He was getting moving OK, then changing up thru the gears as quickly as he could, and only then trying to set Cruise Control while he was pulling the highest gear at the lowest revs he could for any given road speed - and the computers simply wouldn't let him set Cruise cos he was in too high a gear and his revs were too low!! :shocked:
There's not too much in this with the 1330 Triple motors; waaayyy more with the 998 V-Twins, but it's something to watch out for! Simple solution tho, I told him that whenever he couldn't get Cruise Control to select, it was most likely cos he was
in TOO HIGH of a gear for the given revs and road speed, so he needed to either change down, rev up, or both! :lecturef_smilie:
Funnily enough, that worked for him, and he found he could select Cruise Control in every gear and at speeds right down to his usual suburban 'tooling along' speed!
hyea:
He went away happy, later reporting back to me that he was generally riding at least one gear lower than he had been for any given road speed, sometimes two; his Spyder was
MUCH more responsive than it had been, it felt & responded like a much lighter machine;
AND he discovered that over time, he started to get noticeably better fuel economy too!!
That was probably because he was now keeping his Spyder's engine revs
IN the most efficient rev range rather than riding around with the revs a touch (or more??) below that level!!
So, maybe that's something for you to consider Old Prof; and if not, maybe it'll help someone else?! :dontknow:
Good Luck! :cheers:
