Ducati Indiana

Ducati Indiana 750

With Phil Aynsley


The mid ‘80s was an interesting period for the Italian motorcycle industry… and resulted in some equally interesting bikes being produced. At the forefront of this time was the urge to market factory ‘choppers’ mimicking the Japanese factories offerings.

Morini had their Excalibur and Moto Guzzi the Florida – and Ducati had the Indiana! All were memorable sales flops.

The Indiana was amongst the first new models developed after the Cagiva takeover in 1985. It was introduced in 1986 and was made in three capacities – 750, 650 and a 350cc version for the domestic market.

The square section full-cradle frame was similar to that of the Elefant, but newly designed for the Indiana and featured a rake of nearly 33º. The motor was based on the 650 Alazzura’s but with a wider spread of gear ratios and Bing constant-vacuum carburettors. The 750 version featured different exhaust headers and collector, head, tail lights and dash.

The Indiana was not a success (surprise!) with only about 2,250 of all models being built (1,800 being 650s). Police versions of the 650 and 750 were offered from 1988 through to 1990 but only 64 were produced. The 750 made 53 hp at 7000 rpm, with a dry weight of 180 kg.

Kengo Kiyama Honda CB500R

Honda CB500R Racer

With Phil Aynsley


The interesting thing to note about this Honda CB500R is that it was the product of the company’s Research & Development department, not the Racing department (RSC).

Based in Saitama, the R&D’s first design was built in 1971 and used the road-going CB500’s frame. It was raced by Morio Sumiya in that year’s All Japan Championship. For 1972 this much more focused bike was constructed and was ridden by Kengo Kiyama in the Open Class, winning several races.

It used a CB500 motor as its base with the capacity increased to 651 cc (64 x 50.5 mm). Numerous modifications from the stock motor included the following – the crankshaft was machined from solid; high-compression pistons with only two rings; dry-sump lubrication; larger, magnesium oil pump; magnesium sump and (smaller) oil filter housing; dry clutch; sand-cast cylinder head with magnesium valve cover; larger valves with stiffer springs and hardened seats; close-ratio five-speed gearbox; Kokusan electronic ignition. The Keihin 31mm carburettors were the same as used on the CR750.

The frame was made from chrome-moly steel, using 25mm diameter tubes, while the forks were also from the CR750. Power is 80 hp at 10,700rpm, with a dry weight of 138kg.

This bike was first displayed at the 1971 Tokyo Show and after it was retired kept in storage until Italian mechanic Carlo Murelli was offered his choice from Honda’s race bike collection as a retirement present after many years of working in Japan for Honda RSC (then HRC) on the NR500 and NS500 projects, amongst others.

Prior to joining Honda he worked on race tuning CB500s during the early ‘70s in Italy. In 2016 this bike was auctioned in the UK bringing in just under AUD$150,000.

A rare Gilera 500/4

Original Gilera 500/4 racer

This is one of the very few remaining original Gilera 500/4s, rather than a modern replica. Only fifteen were constructed during the decade plus they competed for.

Its original motor is “on the shelf” and another period motor (with providence) is now installed. It was a factory bike, raced in 1957, then retired when Gilera (together with Mondial and Moto Guzzi) quit GP racing at the end of that year.

In 1963 however Gilera returned to competition (using the very same ’57 machines) with the “private” Scuderia Duke team. The factory continued to race the bikes, with a number of podium placings, right up until the end of the 1966  – not bad for a design that traced its beginnings to the pre-war water-cooled supercharged Rondine (1939 Gilera 500 Rondine – Link).

When Gilera returned to racing they did so with the 1957 Gilera 500/4

The air-cooled, post-war version first appeared in 1948 and was designed by Ing. Remor (who moved to MV Agusta at the end of 1949 and designed a very similar motor for them), Gilera went on to win the Rider’s Championship in 1950 (Masetti), ’52 (Masetti), ’53 (Duke), ’54 (Duke), ’55 (Duke) and ’57 (Liberati).

Ducati 125 GP parallel twin GP racer

1958 Ducati 125 GP Twin

With Phil Aynsley

Following on the the previous column that featured Ducati’s first multi-cylinder motorcycle (Link), I thought it would be good to look at Ducati’s next attempt at a parallel twin – the 1958 125 GP bike.

It first raced at that year’s Italian GP at Monza and was part of one of the company’s most notable racing achievements, taking the top five places in the 125cc race, throughly eclipsing the MV Agusta team.

The Twin was ridden by Francesco Villa and finished in third place behind winner Bruno Spaggiari and Alberto Gandossi and in front of Dave Chadwick and Luigi Taveri – both on better handling Ducati singles.

The 125 twin had a bore of 42.5 mm and a stroke of 45 mm

The 125 Twin made 22.5 hp at 13,800 rpm but the three camshaft Desmo valve gear allowed a maximum of 17,000 rpm to be touched on over-run if required. A six-speed gearbox was used to try and keep the revs within the narrow power band.

Frame was a double-cradle and it rolled on 17-inch rims

It was the combination of the peaky power characteristics, the relatively high weight of 92 kg and an output that was barely more than the 125 Desmo single which saw development of the Twin basically cease with only three being built.

The Twin again finished third in the following year’s Monza GP, this time with Taveri riding. After that it was campaigned by Ducati’s partner company Mototrans in Spain beginning in 1962, where Bruno Spaggiari won numerous events.

Fuel was supplied by a pair of 23 mm Dell'Orto carburettors - Compression ratio was 10.2:1

Mototrans did continue to develop the bike which saw maximum power increase to 24 hp at 15,000 rpm, together with a wider power band. The Twin was raced in Spain (and also in Italy) right through into the 1966 season. Ducati’s 125/4 (to read more about it click here) was designed to be the replacement for the Twin in Spanish competition. The bike seen here is Villa’s third placing Monza machine.

Ducati’s first multi-cylinder motorcycle | The 1956 175 Twin

1956 Ducati 175 Twin

With Phil Aynsley

The 1956 175 Twin has the honour of being Ducati’s first multi-cylinder model and was first seen at that year’s Milan Show (where it was christened with the nickname “Il Testone – Bighead”.

A 1956 Ducati 175 Twin restored by Alan Cathcart

The 180º DOHC design was not a Desmo but was a twin over-head cam driven by spur gears from a jack-shaft between the cylinders. Both the fly-wheels and big-end were machined from steel billet and all gears were drilled to reduce weight.

The 175 Twin had a single competitive outing – in the 1957 Giro Motogiro d’Italia resulting in a DNF for rider Leopoldo Tartarini.

Ing. Fabio Taglioni used the basic design (although now with Desmo heads), in his later 125, 250 and 350 GP parallel twins.

The 175’s dry clutch was replaced by a wet clutch on the later bikes. A design feature that did carry over was the use of expensive Hirth couplings to join the separate flywheel assemblies.

With development resources being concentrated on the Grand Prix singles and twins the 175 was sent to the US to race and hopefully generate some publicity for Berliners, the American Ducati importers. After some time (and no great success) the bike was returned to Italy where it was eventually obtained by Francesco Villa.

Villa then bored and stroked the 49 x 46.6 mm 175 into a 55.2 x 52 mm 250. The frame was replaced by a scaled up version of the 125 Twin’s while the Ceriani forks and Oldani brakes were replaced by Marzocchi and Amadoro units. It is this form that it appears here.

In original 175 cc form the bike produced 22 hp at 11,000 rpm and weighed 112 kg, while top speed was around 175 km/h. As a 250 cc the claimed power was 39 hp at 12,000 rpm (actual 30 at the gearbox) with a dry weight of 118 kg.

Only one other 175 Twin is known to exist, in the US. This bike went through many hands before finally being restored by well known journalist Alan Cathcart.

1994 Suzuki RGV500 XR84 | Kevin Schwantz

1994 Suzuki RGV500 XR84

With Phil Aynsley

This is Kevin Schwantz’s 1994 factory XR84, on which he won the Japanese and British GPs before finishing a close fourth in the championship that year, three-points behind Kocinski on the Cagiva and five points behind Cadalora on the Yamaha – while Doohan was a whopping 148 points in front. The original number 1 plate has been replaced by Kevin’s more familiar number 34.

A broken arm from a mountain bike tumble had hurt his preparation and made him miss crucial pre-season practice and only gave him three weeks to regain his strength. He was quickly back in form by the third race, winning in Japan. With three more consecutive second place runs, then a heroic win in Great Britain with a broken scaphoid and dislocated wrist along with aches and pains from a violent crash in practice, Kevin seemed poised for another shot at the championship.

That was until Laguna Seca where Schwantz went down at the famous corkscrew, dislocating his left hip and fracturing his right scaphoid. He therefore decided to sit out the remaining races in the ’94 season and have an operation as soon as possible to be able to begin winter testing earlier in preparation for the ’95 season

The 1994 motor was a reed valve V-4 with a 70º V angle (later motors had various angles, up to 80º) and used a dual power valve system.

Moto Guzzi has a long history of being a prime supplier of police and military motorcycles, with one of their first being the 1936 G.T. 17.

That model evolved into the G.T. 20 then the far more numerous Alce (Elk) that was used by the military during WW II. All these bikes used the proven 13 hp 500 cc (OH exhaust/side inlet valves) motor.

Bultaco Streaker 125 two-stroke racer

Bultaco Streaker

With Phil Aynsley

One of Bultaco’s rarer models was the Streaker, with only 750 odd examples of this 119 cc two-stroke single produced between 1977-1979 in the black model and 1979-1984 in the white A model.

The Bultaco Streaker weighed just 85 kg dry and was good for 116 km/h

Obviously aimed at the racing mad youth market the Streaker was quite a competent machine. Output was an advertised 13.3 hp at 9000 rpm (in reality closer to 10 hp) with a 85 kg dry weight, enabling a real world top speed of 116 km/h.

Despite receiving the 125 designation the Streaker was a 119 cc single-cylinder

The 119 cc (advertised as a 125) model was supposed to be mainly for export markets, while a 75 cc version, that used the same chassis, was to be for domestic consumption. The 75 was also used as the basis for a “single class” race series with one notable rider to get his career underway in it being Sito Pons.

Bianchi’s post-war motorcycles

Bianchi’s Aquilotto, Bianchina & Falco

With Phil Aynsley


Following on from the previous column I thought I’d round out the look at Bianchi with some of their post war bikes.

PA Bianchi Aquilotto
Bianchi Aquilotto

During the 1930s the company started producing trucks but the factory was destroyed by bombing during the war. To re-establish the company, the Aquilotto (Eaglet) clip-on motor was put into production. This 48 cc 2-stroke motor was designed to be attached to a bicycle in much the same way as Ducati’s Cucciolo motor, to provide basic transportation.

A full motorcycle, the 125 cc Bianchina 2T, appeared in 1947 and proved to be a success, also helping the company recover from the destruction of their Milanese factory and the death in 1946 of Edorado Bianchi, the founder of the company.

PA Bianchina

Lino Toni was employed in 1950, and together with Sandro Colombo, designed a 250 cc parallel twin 4-stroke for GP competition, this proved to be too heavy and was subsequently enlarged to a 350 cc then a 500 cc machine – in which guise it did show some promise.

Back on the street a wide range of models were produced in the ‘50s and ‘60s. This Bernia is from around 1963 and had a 125 cc OHV 4-stroke motor. It and the 173 cc Tonale, also a 4-stroke single but with a chain-driven OHC, were two of the best known of the company’s later models.

Well that would be Bianchi! Of course the said products are bicycles but the company also turned out a range of highly advanced motorcycles from 1897 to 1967. During its long history trucks and cars were also made.

While Edoardo Bianchi’s first, 1897, design was a motorised bicycle, by 1903 leading link forks were fitted and in 1910 a 500 cc single really established the company in the motorcycle field. A variety of designs appeared over the following years including 600, 650 and 741 cc V-twins, side valve and OHV 350 singles and an OHV 175.

By 1925 Bianchi was (like almost every other Italian motorcycle manufacturer) racing. Except those other companies didn’t have Tazio Nuvolari as their rider! He won the 1925 350 cc European Championship (which was a single event at the time), won the Nations GP four years running from ’25-’28 and Circuit Lario five years running (’25-’29).

The bike Bianchi used for competition was a DOHC 348 cc single designed by Albino Baldi. In the 1930s he followed the 350 up with an OHC 500 single, then in 1938 a 500 cc supercharged DOHC four (which was not fully developed before the war intervened).
