New Bike.

Hi Andy and congrats on the new purchase. The Bonneville suspension replacement usually comprises of TEC front springs and TEC or Hagon rear units.

You'll need to change the exhaust pipes if you want it to sound right.

 

That sounds like a good low mileage bike.
I don't want to pee on your bonfire but it's always nice to know the history, Dozers Dad and Rich Bryce can advice you on that.
My Bonnie EFI is a 2012, I bought that with 2035 miles on the clock, it's now done 9k and I love it.
Bits you may consider adding/changing:
Scottoiler
Rear shock upgrade
Progressive front springs upgrade
Fork gaiters
Centre stand
Locking fuel cap
Rear rack
Bikini fairing

 

Good stuff mate I like your choice but be prepared for some serious tinkering

 

Burton Bike Bits are well known and long established in the older Triumph circles (Meriden) so should be okay to deal with. Seems that way anyway.
Never knew that Dunstall produced rear shocks though. Hmmm.
Hagon, and some others, will make up new rear shocks designed specifically for your weight and riding requirements, which may be a better way to go. Have a word with Hagon themselves to see what they can offer, and indeed any others that are recommended by the other inmates hereabouts. At least you have time to do a little research before delivery, but ride the bike first to see if it needs any alteration(s) to make it as you would like it.
Methinks you have much pleasure coming your way - and plenty of suggestions as to how to get it.

 

Very nice Andy.
The plain white looks great, Triumph rack already on, so that's good.
Get your centre stand fitted first, it will help when cleaning.
Bet you can hardly wait!

 

I am pretty sure Hagon progressive fork springs are Wilbers items for which you pay £10 more.....they use the same stock number and near identical packaging. I fitted them to my T100 with Tec shocks for a much less jittery ride.
The feked.com Vickers pipes are also well worth a look. 'Manly' but not offensive! With a TTP retune as well the mid range torque is significantly boosted and with it a much more tractable ride.

 

My SE is a 2012 bought with 1800 miles on the clock from the local Triumph Dealership.
I have fitted TEC progressive shocks at the rear and their progressive springs at the front. Both easy jobs done literally in minutes - watch Delboys videos if not sure. TEC are cheap - Hagons would be better but Ohlins will be over the top for a Bonnie I think. The Dunstalls look like the TEC ones but TEC are £99.99.
Check out their site for other parts - like a centre stand. http://shop.tecbikeparts.com/t/triumph-twin-parts
Exhaust should be next priority unless you want the bike sounding like a sewing machine! Lot's of choice - TEC again, Triumph TORS, (which I have) Arrow, Norman Hyde and so on.
Fork gaiters improve the look of the bike and then the list goes on!
