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.
