Both are 9 years old... and the rear one is dead (5000 kms, at the limit when I bought the Estrela, 6500 now, really dead in the middle). Autumn, with its rain, is really here now, so I must change it! Is it normal, only 6000kms?
I do not know yet if I will choose the BT 45 or keep the original Accolades. I understand that the BT45 are better, but the Accolades have a better "look" for Estrella old style...
First thing to do on my new 1994 Estrella has been tires replacement. The bike I bought has still the 25 year old originals (two pieces of glass ... to throw away) but I find that replacing them is a very hard. a) original sizes hard to find, almost impossible. b) at present problems with tire availability due to the logistic international crisis. c) hard to find tires that respect the original diameter in order not to modify bike dimensions (trail, etc...) and final gear ratios.
This is the solution I found. It is a slight illegal, but luckily in Italy it is not such an important problem ... The stock Bridgestone Accolades have a diameter of 619mm at the front, and 628mm at the rear. Finding two tires that are almost identical in size is quite impossible. Furthermore, the choice is restricted by rim size: many new tires ask for a wider rim, main at the rear.
Bridgestone BT 45, which seems to be the most reliable solution has these problems: out of production from more than 3 years, so you find just old tires. BT 46 is good, they offer a front 90/90-18 620mm diameter for rim 1,85” (perfect), but the problem is at the rear. Bridgestone have a 120/80 (624mm) or a 130/90 (639mm) both for rim minimum size 2,50” and only tube type. Anyway no way to find the available rear size product.
After a long search between suitable sizes, product availability, tires that were good in pairs, quality and performance, I finally found the solution, at least for me: the excellent Avon RoadRider mk.II. The front is like the original a 90/90-18 and has a diameter of 619mm, at the rear a 120/80 with a diameter of 629mm. The only problem at the rear is the rim width. For the Avon there is a 2.50 ", that of the Estrella is a 2.15, but when the tire is mounted it has been seen that the profile remains acceptable, even on the narrowest rim. On the next months I’ll inform forum about my experiences with these tires.
Welcome Silvano, Thank you for your detailed Information. I will be careful with my 45s - I think they are from 2015 but really good. I am lucky that it is so easy to find 8-Inch tyres for my Lambretta. Have a good ride Roger
After 6.000 km with the Avon Road Rider Mk II tires I can testify they are an excellent choice.I say ideal at least for me. Handling has improved a lot. Cornering is instantaneous, you can enter a corner with brakes quite till apex point. The safety that the bike gives is always excellent, the front is solid and goes where you want it goes. Above all, you enjoy excellent the balance, it feels like riding a sports bike despite the set up is not yet optimal, as I mount a pair of Wirth springs at the front but I still have the old shock absorbers on the rear of which only the spring works after 25 years, hydraulic is dead.... Virtually zero rubber consumption. Good wet performance.
