Riley - Riley Sidevalve
The Sidevalve Riley was available from 1919 originally as the 11hp, having a 65.8x110mm engine with an RAC horsepower tax of 10.8hp, with the sports version of the 11hp marketed as the Redwing, which is probably the model best known today, along with the well known sand racer. For 1925 these Riley Sidevalve models were fitted with the new well base wheels which were being adopted onto cars in the UK (although already popular in the USA) with the Riley models 11/40hp (1498cc) and 12hp (1645cc). Front wheel brakes also made it onto the sidevalve Riley by 1925. These Riley Sidevalve models were listed to 1928 after which the Riley company concentrated wholly to their entirely new 1,100cc range.
The Riley Sidevalve tyre size listed between 1919 and 1924 was the beaded edge 760x90 size, and Blockley produces the best example of the 760x90 tyre size. For the side valve model Riley built after this time the wheels were the later well base artillery type with tyre size quoted 4.50x19 (called in period 27x4.4), while the largest 1645cc engine example was listed with a larger 5.00x20 (29x4.95) tyre size. Blockley produce superb, period authentic examples of all three of these tyre sizes, which are the very best tyres you can fit - see full details of all the options for the Riley Sidevalve tyres at the links below. We also make a large range of other tyre sizes should an owner require something else.
