Final mods for Bonnie...For Now

I'm finally done with all the modifications I wanted to make to Bonnie, at least for this year. First up was installing the factory heated grips. They're pricey but the best part is that they connect to the wiring that's already in the bike that not only heats the grips but also shows the status on the clock display.

Next up I wanted to address some of the handlebSar ergonomics. I was getting a little bit of shoulder pain on long rides from reaching forward so I got 20mm Super Corse handle bar risers. I was also slightly bothered by the non-centered location of my phone when mounted on the handle bar quadlock mount so I bit the bullet and bought the billet aluminum quadlock handlebar clamp mount. It's an expensive piece but is beautifully made and perfectly centers the phone mount. Noting here that the bottom bolt for the clamp was torqued to 30Nm and the hex bolts for the clamp was torqued to 24Nm.

I've got a Dynamo Moto bike stand on the way to make it easier to move the bike around the garage so I needed rear bobbons for the stand. The Motone Axlerod bobbins are perfect for this. It goes through the hollow axle and has the added benefit of keeping dirt and gunk out of there.

For a little dress up with some functionality, I got a Moton oil cap and shift peg as well as a British Customs retro chain guard.

Lastly, I still want a rear grab bar but the factory one I installed a few weeks ago blocks the brake light so I got a Motone grab bar instead which is curved up to not block anything. Oh yea, my new license plate arrived too ;)

While I was at it, I also adjusted the rear preload. The manual for the Fox shocks indicates that 0 preload is for an average rider (around 170-180lbs) and 7.75 turns for a 2 up ride situation. Since I weight 250lbs without gear, I set the preload to 6 turns. Overall the handling and comfort of the bike improved a lot and so did the ergonomics.

New Front Sway Bar

After the unfortunate sway bar failure I had at NJMP a few weeks ago, I ordered a new Karcepts 1.25" front sway bar to replace it. I realized that if the car handled well with no bars I didn't get to get as crazy of a bar as I had before so I went down the the more normal "big size" front sway bar and only set it to the 2nd hole from full soft.

Obviously the rear bar was now reconnected as well and I left that at full soft. We're heading back to NJMP in 2 weeks so looking forward to see if this makes an improvement or not.

Also, I noticed at that event that my AC was no longer blowing cold so had SJF refill the freon and now the vent is pumping out 50F ice cold air at full blast.

Bonnie’s First Service

I’ve been having so much fun on Bonnie that I logged 600 miles in just 3 weeks even though I only ride on the weekends. That means the engine is finally broken in so I took it back to the dealership for its first service.

Flyscreen and Fender

I wanted something to keep the bugs off the clocks and my phone so I picked up a Dart Piranha tinted fly screen. I'm pretty sure it's useless for anything other than that since apparently even the slightly larger ones just redirect air to your helmet instead of your body. I kind of prefer the fully naked look but a short fly screen like this still looks proper on this bike.

Also, with the tail tidy in place, the front fender looks disproportionally small so I replaced it with a shorty matte black aluminum fender from Brogue Motorcycles.

Remus Exhaust and Tail Tidy

Now that the suspension is sorted, I wanted to take care of some cosmetic and sound changes. While the standard pea shooter exhausts are classic and sound pretty good stock, I wanted to change it with something that had a slightly deeper tone and upswept so I can clear the axles to install some Motone Axlerod bobbins later.

For the exhaust I opted for a Remus slip-on muffler setup from Austria. I'm not really looking for a performance gain here since I'm more than happy with the factory power output so this was just a cosmetic and auditory enhancement. Since I don't anticipate having any passengers I also took the opportunity to delete the passenger foot begs for a cleaner look since they had to be removed to install the new mufflers anyway.

Next up were some lighting enhancements. I removed the giant rear fender and light assembly with a British Customs tail tidy with cateye brake light. For the turn signals, I went with Brogue Motorcyles classic LED turn signals in the rear which I soldered to a A&J Cycles plug-n-play wiring kit and mounted using their shock mounted brackets. For the front I went with the same Brogue Motorcycles classic LED kit but they offer one that had the correct plug-n-play connectors for the 2026 T120 model. Since the LEDs offer less resistance than the factory halogens they flash too quickly. Thankfully Triumph already solved this problem and you can reconfigure the lights using the cluster to take into account LED lighting but setting it to mode 2.

Another thing that I wasn't too happy about were the factory levers. I felt they had too much play in them and were also unequal looking left and right. I replaced them with some much nicer fully adjustable Motone black aluminum clutch and brake levers and not only do they look great but they feel perfect too with no excessive play. For added decoration, I replaced the factory plastic brake reservoir cover with an aluminum Triumph logo one.

Finally, I replaced the silver clutch over plate with a black Triumph Motorcycles one to give it an even more blacked out look and also replaced the clutch guide with a Triumph black aluminum one.

I even got my new Triumph gloves which are super comfortable and look pretty good.

Suspension and OEM+ Upgrades for Bonnie

The T120 comes with a decent KYB suspension setup from factory but why settle when you have plenty of options. Specifically, Triumph has an OEM upgrade made by Fox Shocks that just made too much sense not to pursue. Not only are these better dampers but they include an external reservoir and have compression adjustability.

The installation itself was pretty straightforward since I had the dealership install the factory center stand. Each side is just held by two bolts. In order for the new bolts to install properly, it's important to get the threads clean off any loctite so that they can be torqued properly. The threads are M8 x 1.25 so I used a tap and die kit to clean off the threads before installing. I set the compression to the recommend 18 clicks from full stiff (10 clicks is Sport and 23 is Comfort)

For the front suspension, I installed TEC Progressive fork sprinks. This should make the ride more compliant on small bumps but stiffer under braking.

I wanted to add some engine protection in case I ever drop the bike so I installe the Triumph engine bottom guards.

I also wanted to add some protection to the radiator so I added a Monotone union jack radiator guard.

The weak horn was also another item I wanted changed. I wanted to make sure I'd be heard if I honk the horn so I replaced it with a Denali Soundbomb Mini Horn in its place. The sound is now loud and deep. It's basically a car horn now.

Finally I added a helmet hook on the right side so I can secure the helmet if needed and replaced the seat with a Motone Rattler cafe racer style black seat. I loved the contrasting brown seat but unfortunately they don't make it in brown.

I have to say I think it all came together nicely and it's getting closer to what my vision for the bike should be.

Fixing the Automatic Climate Control in Mando

One of the things that wasn't working on Mando was the automatic climate control. Yes, the heat and AC work bot only when manually set. The sensor for the automatic climate control is located the overhead console where the map lights are. Unfortunately you can't just buy a new sensor and finding a new overhead console is next to impossible. I took my out to get the part number and starting searching Ebay. The first part of the part number indicates what modules are enabled. Since I have the C55 AMG, I had pretty much everything imaginable including the SOS button so I can't just buy any W203 overhead console without also maybe decativating features it doesn't support so it doesn't throw an error. The last part of the part number after the slash is a color code.

I was able to find a used overhead console on Ebay with the exact part number I needed but with a slighly different shade of gray. It was cheap enough at under $100 so I figured it was worth a try. I was able to swap it in and sure enough, the automatic AC started working again. While it was out, I also switched the front and rear dome lights to LED.
