    Has anyone replaced stock fork springs with the TEC progressive springs ? Thoughts ?

    Sorry for the delay. I just swapped seats. Seat of the pants says the Corbin is maybe 1/4-1/2” taller feeling at a stop, but maybe a bit lower when riding. I think that is a result of the deep scallop to the seat. While there is little rear movement available, the seat is A LOT more comfortable than stock.

    I did today. It was a pretty easy job but I had to use a breaker bar with the 30mm socket to loosen the fork cap nuts. I also installed the TEC adjustment caps. It seems like it should be a worthwhile upgrade. The OEM springs are only linear, and rather short - the OEM plastic spacer is almost as long as the OEM spring !

    The Speed Twin only has 120mm of travel up front, the springs only need to be so long for that.

    What is the spring rate range for those TEC springs? Do they sell different versions depending on your weight/use?

    According to the TEC website no, they dont sell different progressive fork springs for the Speed Twin - just the one set because they are progressive and you can add their preload adjusters to dial them in for your style/use/weight.

    Did you measure sag with the original springs and now with the new setup to check how they compare?

    Sorry no, and there is too much snow on the ground here now to even ride and get some feedback. The previous owner had put on Ohlins rear shocks but the springs were for a 160LB rider. I changed the springs to proper for my weight (250) and they made a big positive difference.

    That does look good but, it seems like the bars would be too low & a bit to much pull back/sweep to be comfortable for me.

    A Speed Twin has been on my radar for awhile. Is this an engine that begs you to open the throttle and go, or is it happy to roll along at a reasonable speed?

    Bikes that made me want to twist the throttle, hold on, and do stupid things. Ducati ST3, don't laugh, Goldwing 1800, Kawasaki RS 900 Cafe

    Bikes that were happy, for me, to cruise Harley XR1200, Suzuki VX800. BMW G650, NC700X.

    Bikes in-between BMW R1200RT, FJR 1300

    A nice used example turned up. A test ride would be in congested city traffic. No real answer there.

    I've ridden my Dad's 2017 Bonneville. I think it's a T-100. It's OK, but kind of a yawn.

    It has pep in it's step. The exhaust note when wound up is very satisfying in stock form.... Arrow slip on exhaust and a Meerkat crossover pipe does not disappoint at all either IMHO...

    The Speed Twin can absolutely be a hooligan bike, but it doesn't look like one. Very happy with mine.

    The same engine is in the 1200 scramblers (high power) vs the bobber/speed master (high torque). Don't let the designation fool you. They are happy to burble along but can spin up nicely (not as violently as a inline four).

    Cheers,

    Actually, it is the same basic engine across the line, with the Scrambler engine being in the middle.
    The Speed Twin and Thruxton are both higher hp versions.
    Either way, you should not be disappointed. :D

    The engine is a peach. Will quite happily bop about the back lanes at 25mph. Or whack you out a corner on a wave of instant torque in any gear. (Snappy gearing)

    Jumped back on my CrosstourerDCT and went for a 60-70mph top gear overtake and was shocked at not being blatted towards the horizon like the Speed Twin. Had to remember to drop a gear or two.

    It looks sensible (I like,) but is well capable of being proper naughty (I like even more)

    Its wilder side is though kept in check by the budget suspension (100kg kitted here) offset with a surprisingly sharp chassis and front brake. Will be making my own "R" version in time.

    Its not similar to any of the bikes you mention. Kwack Cafe with a ST-3 engine but lighter feeling, maybe?

    Not according to Bike magazine - there are only two states of tune for the 1200 twin. There might be slight variation due to exhaust and intake routing. I would agree on the not being disappointed part.:thumbup

    Everything I've seen shows the Bobbers and Bonneville lines with a claimed hp of 77, the Scrambler at 88 hp, the Speed Twin at 96 hp, and the Thruxton now at 104 hp.
    I can see differences between the Scrambler and Speed Twin due to different exhaust and/or intakes but not between the Thruxton RS and Speed Twin.

    All you part time Triumph salesmen convinced me to go look at the bike, this Friday.

    I'm not wild about the bags. They will be removed.
