A SUGGESTED review for the benefit of new owners of Modern Classic (W/C) twins

I had previously mentioned the concept of this type of thread (hopefully not a duplication), and some thought it a good idea, so for whatever itís worth here goes;
Following is a list of defects, and potential trouble areas that seem to have been ďdesignedĒ into the new Modern Classics that debuted with the introduction of the Street Twin in 2016. Since my experience is just with a T120, Iím sure that I have missed a few items applicable to other models, and therefore encourage others to add to the thread.

1. Front Brake groan at slow speed, mostly T120ís. The fix; floating rotors & some dealers have replaced the entire front wheel with one with a rubber dampening pad.

2. Handle bar shake at speed. Lots of things to go wrong here, and varied opinions. Important factors here are, tire age, tread wear, rim trueness, wheel balance, and bearings from wheel to steering neck.

3. Side stand safety switch magnet falls off. Mostly an affliction of early models, (I believe). If this happens, the motor will stop when the transmission is placed in gear. I.E.,the bike thinks you're going to ride away with the side stand down.

4. Fuel pump harness recall. See dealer for this recall if the bike has not had it done.

5. Main wire bundle (loom) on left side of steering head too tight. This means the cable bundle may be feeling stress and tension when the bars are turned full right. The easy fix , hopefully for the long term, is to move the fuel tank back about 2 inches until the small black plastic cable clamp is exposed. Loosen its two screws and move the bars far right, push the cable a bit in that direction and re-tighten the two screws. Use your best judgement to determine if the cable is now stress free full right. Also, remove and leave free the clutch cable from under the clamp. (See #8) This appears to be an important area to watch for wiring issues, in general. (See #11)

6. Poor light beam from O.E. M. T120 head light. Easy fix is to install the headlight assembly from a Street Twin or T100 . I used part # T2706508, Head Lamp w/ Bulb Shield. Or use and after market replacement. Warning, there is a small connector in the headlight bucket easily broken if not careful.

7. Motor oil leaks from: A. Sensor O-rings under right side front sprocket cover. This is a quick and easy O-ring replacement fix. Warning, be careful not to mistake this leak for just excess chain lube accumulation.
B. Weep hole in center of motorís base pan. Coolant or oil can leak from shaft seals on the oil & coolant pumps. Or oil from the O-ring seals on the tube through the base to the block. More complicated repair, get it done under warranty if possible.

8. Clutch cable rubbing and wearing away insulation on wire bundle. Triumph finally posted a recall on this; SRAN560F or NHTSA19V133. Simply removing the clutch cable from under the clamp may be all you really need to do. You need to watch this area for abrasion of materials.

9. While this is not really a defect, I will mention that these machines (at least the T120) seem to have a high center of gravity, meaning that they feel top heavy and easily dropped if you get it over too far. For example, moving it in or out of the garage, or during parking maneuvers. Judging from the number of members who mention dropping their machines, I think this is a factor new owners should be mindful of. (See # 10.)

10. Damage to transmission shift mechanism from left side drop. You will know right away something is not good with the transmission. There has been at least one very good thread on this repair. If youíre not clever with tools, your bike is going into the shop.

11. Wire breakage at voltage regulator connectors, T120 / 100. This is a new one that has just been posted. The voltage regulator / rectifier is mounted on the front forks , and thus moves with them flexing the connecting wires, apparently, over time, too much causing them to break. Some owners are moving this device to a fixed position on the frame. We may see more of this one as these bikes age with mileage.

Then there are the 3-4 reported T120s that stopped downshifting for no apparent reason. Once corrected under warranty (or by the owner, in one case) the problem does not seem to recur.

In fairness, I think the danger of such a list is that someone seeing it but not otherwise familiar with the T120 will think that the bike is problem plagued mess and steer clear of purchasing one, new or used. I bought one of the first T120s in the US, and it's been great for well over three years now. It's been the best all-around bike I've ever owned, not to mention the smoothest, with by far the best gas mileage.

My bike was included in the fuel pump harness recall, which of course does not effect later bikes and has now been corrected on earlier ones. I also installed the excellent headlamp from the T100. I noticed the tight wiring around the steering head the day I brought the bike home. The fix was to remove the plastic bracket, let the clutch cable hang free, and move the harness forward a little before reinstalling the bracket. I've had no electrical problems, and no damage to the harness.

Otherwise, I've had none of the problems listed.

So far I have had no problems at all with my 2016 Thruxton S, have had it for over 15 months now got it with the fairing kit at a good price because old stock, the only things so far was 2 recall fixes, but my bike didn't suffer any problems before the recall notice, so not all Triumph have problems.

My T120 Black is almost 3 years old. Radiator was replaced due to a leak - fan touch during assembly(warranty), front wheel assembly replaced to brake intermittent squeal (warranty), all recalls complied with (no actual problems found), just for future resale, IF I ever sell it. Other than that, bike has been a dream. I reckon its pretty minor really and the riding pleasure far outweighs any small inconvenience. Just for giggles, my son and I test rode a couple of H-D's last weekend. Yeah, nah! Bonnie all the way!

And one more item to check;
#12: The engine balancer access plug, lower left side of engine case just above the shifter peg, and about 25 or 30 mm in diameter has occasionally been found to be loose, and needs to be snugged down. Maybe even a little blue thread locker would be in order here.

Addendum; Buyers of motor vehicles, including motorcycles, often find themselves as unwitting Beta testers, particularly with the first release of new designs.
It is inevitable that some flaws will be built into new products, as manufacturers must balance testing duration, and costs in a race against the clock to bring new products to market. Investors must be rewarded!
The purpose of this list is to bring together a summation of notes found elsewhere on this website in the hopes of making a very good product even better, and allowing new owners greater satisfaction and refinement of their machines. (Or at least avoiding a roadside breakdown!)
And thanks to TSMGGUY for reminding me about item #12 in his post under another thread entitled T120, Oil Leaks.

There’s a T120 recall for brake squeal?

thank you GEB for a well written and honest post, if this stops someone from buying a triumph good. i know that my 2016 street twin will be my last triumph . not because of the defects which are all legit by the way , but because of triumph corporate response to these issues , they are really trying to sweep things under the rug so to speak , i,am purposefully trying to keep my mileage low so as not to wear out said wire harness ,and also try not to go full lock to lock .i did some silicon taping of my harness once i notice the wires showing through the wrap. did the clutch cable thing , had my kick stand magnet pop out so i was stranded and the dealer could not guarantee me that they would send me the revised model on the 2017 and later.glad my fuel pump harness hasent started leaking yet cause my dealer gave me the run around even with that but the official fix wasn't recalled yet. brakes squeak at low speed . does it really cost so much to put a floating disk on especially the front. however i still really love it , i just dont trust it enough to put alot of miles on it. ill take my good ol yamaha out. the triumphs only for the occasional sunny day .

I procrastinated on having the fuel pump sub harness replacement recall done. That was a mistake. The harness started leaking fuel all over the hot engine one morning. Have the work done, if you haven't already. If your bike is not one of the earlier bikes covered by the recall, then you're good to go on this.

No recall on brake squeal, but replaced under warranty. Funny thing - it didnt start till about 5000kms and slowly got worse.

People dropping bikes pushing out of garages is purely down to bad methods, nothing to do with top heaviness, and not Triumphs fault in any way. I have had my harness replaced under warranty after being stranded 350 klm from home, still think the T120 is one of the best all rounders I have had in 40 years.
